I have an idea for a character. Im a tabaxi. I was thinking of starting off as a rouge. Then going into barbarian for 3lvls to 5 lvls to get totem warrior. Then possibly ranger for gloomstalker 3 to 4 lvls Then back to rouge. For soulknife. Was thinking also 3 lvls of totem barbarian Then moon druid. I'm not interested in optimization. I like flavor builds. I'm leaning more towards the first one. What are your all thoughts. Stats would be point buy. 14 str 14 dex 14 con 9 int 13 wis 8 char. No modifiers.

As a somewhat metagamer, that hurts.

As a storyteller, I can see the link between a totem warrior barbarian, moond druid and ranger. However, the rogue (especially soulknife subclass, it doesn't seem to mesh well with the very animalistic theme you started with) and the very dark gloomstalker subclass. If you've got any reason (backstory or character theme) for the crazy 4 class multiclass, I'd like ro hear, and maybe find an alternative way to do it (flavour and 0 optimisation are cool until you realise you will die in the early levels and can't play to get your flavourful multiclass) because it seems a little all over the place and not very cohesive. 

If you want advice to achieve a flavourful build, it would help to know what flavour you are going for because I'm having trouble seeing it, is what you described. Rogue is very urban-themed and cunning, whereas totem barbarian is wild and reckless, gloomstalker is sneaky and shadowy (goes well with rogue), while moon druid is wild (goes well with totem barbarian). Soulknife is sneaky and cunning (goes really well with gloomstalker). 

If you want to be sort of a panther-y type: the tabaxi walking silently along the roofs and walls or through the shadows of the back alleys of the city only to leap out and pounce upon your enemies and tear them to shreds. I'd recommend 3 or 5 Gloomstalker + Soulknife Rogue.

If you want to be sort of a lion-y/leopard-y type: the tabaxi stalking through the forests or planes, tracking your prey before leaping out with a wild roar, grabbing & wrestling it to the ground before cutting its throat. Then I'd recommend 5 or 6 Totem Barbarian (bear + tiger) then 3 or 4 - Gloomstalker and 2 - Fighter.

If you want to be sort of a lynx-y type who in tune with the wilderness around them. Then I'd recommend 3-Gloomstalker + Moondruid (but talk to your DM first about how Dread Ambusher would work with WS attacks).

You are trying to do too many things. In the party, you’ll end up 2nd or 3rd best at a lot of stuff, but best in nothing, so you’ll never get a chance to really shine. Don’t spread yourself this thin. You’ll have a pile of low-level powers, but you can still only use one of them per round. 

I think the Barbarian subclass feels unnecessary. It's cool to have resistance to all damage types as a Totem Warrior (I'm assuming you're planning to go Bear at level 3, since it's the most common choice), but as a Rogue you're already able to hide as a bonus action, and making yourself un-targetable provides you with more benefits than Rage. I'd have to know what flavor you're going for, specifically, before I critique the concept too much, but mechanically that first build does not look particularly fun to play.

Gloomstalker is a great subclass for a Ranger dip, since it's so front-loaded with really useful features. Paired with Soul Knife, it gives you a lot of ways to deal damage, plus you still get access to some spellcasting as a Ranger. If I was doing this, I'd probably start with 3 levels of Rogue to get Soul Knife and, more importantly, take advantage of the Rogue's ability to get proficiency in 4 skills instead of just 3 from Ranger. Then I'd switch to Ranger for 5 levels just to get extra attack... then between Gloomstalker and Soulknife you're able to make 4 attacks in round one of combat, since Gloomstalker gives you an additional attack on the first round and Soulknife lets you attack as a bonus action. Although one technicality to keep in mind is that, RAW, if you use Extra Attack technically you can't actually use your Psychic Blades on both attacks... You only manifest a single Psychic Blade when you take the attack action, and it vanishes once used, and the only way to create another one is the class's unique Bonus Action attack. I think a lot of DM's will handwave this... the Psychic Blades aren't particularly powerful, so getting more uses out of them in a single turn isn't going to break the game or anything.

This. Also, OP, I would take a look at what you have in mind and decide which things can be narrative flavor and what mechanical things you need. You can absolutely be a rogue soulknife that worships animal spirits, channeling them into their soulknife without even multiclassing. Most games end around level 10 too, so plan for that to be your endgame with the features you want, and every level past that is gravy.

This is going to be a tyranny of dragons campaign the dm wants to go all the way to 20. A tabaxi or wing tiefling dragon hunter. Tips on the build. 

I'm going to do the wiged tiefling. Thinking of paladin 6 lvl, hexblade warlock 2lvls sorcerer xlvls. I'm open to any other suggestions. Not fixed on any class just yet. Making the character campaign specific.

If you're just looking to be a flying melee combatant hitting enemies with Paladin smites all day long, I actually think Sorcerer is a bad choice. They get a D6 of hit die, and none of their subclasses really feed into a melee combat build. Instead, I'd take Bard, specifically Swords Bard. The main thing that Swords Bard gets you is the ability to add Blade Flourishes using your bardic inspiration die... these can be comboed with Divine Smites, and even the smite spells... it costs a good chunk of your resources, but you can absolutely Nova an enemy with a Smite Spell, a Divine Smite, and a Blade Flourish on a single hit... and if you do this to someone hit with your Hexblade's Curse you get the chance to crit on a 19, doubling your odds of getting a critical hit, which would double the damage of all those things.

It leads to kind of a gimmicky multiclass build... but it's really satisfying when it all comes together and you're dealing insane single target damage to absolutely demolish a major enemy. If you really want to lean into this concept you could take the Vengeance Paladin subclass... They get the Vow of Enmity feature which basically just gives them Advantage on all attacks against a single target once per short rest. It's a bonus Action, so it takes a few rounds to set up if you want them to also have your Hexblade's Curse, but for a Crit-fishing build it's really good.
