New(ish) player LFG online UK (GMT) weekday evenings or Tuesday Morning

Game: D&D 5e
Group preferred: Online 
Experience: I've played a barbarian in a f2f game for a year but would be looking to try wizard which would be new to me, along with the online functionality all being new (I'm good with tech just not used Roll20 or similar properly)
Location/Timezone: UK (GMT/BST)
Availability: Monday, Wednesday, Thursday, Sunday Evenings (2 of 4)
Preferred role: Player (Wizard)
Game style: Looking for a casual-ish game. Have a laugh, cast some spells and kill some bad guys (or possibly some good guys depending on how the story unfolds!)

Extra: I am looking to recreate a character from a book I am writing so I can get a feel for them in person. This means that the standard Wizard template doesn't quiet work. The premise is that the character is a female gnome with low stats who is kind hearted and friendly, but has a rage like state where the transform into an old human male who is cranky and hates but is stronger magically. I would need to talk to the DM about how to balance and create this functionality. I am thinking of a berserker like rage mechanic with limited uses and a bolster to the currently assigned stats which would need to be manually lowered for the "host" character to reflect the jeckle/hyde nature of the character.
TL;DR I want to mess about with class functionality if the DM is happy to.

I am terrible at checking the forums here and my email so please add me on Discord Rek#6057

Thanks
