I tought about this party-oriented build, any critics/suggestions?

Human - Variant

5 Barbarian (Totem Warrior)

4 Sorcerer (Divine Soul)

Feats

Great Weapon Master 

Polearm Master 

Ability Improvement - Strenght

Twinned Warding Bond [3/day]

Rage  -  [3/day]

Out of fight, cast a Twinned Warding Bond. When fight starts, go in Rage to get resistance to all damage (but psychics). Now, 2 mates of your get resistance to all damage, and when they get hit, you get 1/4 of the starting damage

1. Totem Warriors don't get resistance to Psychic Damage, although there might be a race you could take to cover that, I don't know.
2. Warding Bond doesn't specify the type of damage you suffer - including not specifying it's the same type as the original.  Totem Barbarians theoretically resist untyped damage, as their wording is resistance to all but psychic, so I don't think your GM ruling the damage has no type is an issue. 
3. At Barbarian 5 you have 3 rages per day, not 4.
4. You have an implausible number of feats/ASIs.  Even as one of the races (variant human, Tasha's custom) that starts with a feat, you'd have a total of 3 ASI/feats by level 9, not the four you've claimed.

Other than that it looks pretty good to me, although you'll be fairly MAD from needing Charisma 13, which will mean your Dexterity presumably won't be great.

 thanks, you are right about psychic resistance, number of feats and rage/day, i fixed that
