Does anybody know who made the new Caitlyn splash art?

I 3Dmodel as a hobby, and I'd love to make a render of that awesome rifle she has on the new splash art.

I really like to stick to canon so I'd like to ask the artist how does the whole gun look like, since her leg and arm obscure part of the gun in the splash. Maybe there's a sketch somewhere?

Riot / commnunity pls.
