If you want a partner for game art stuff, GamePack Studio - here is pretty solid. They mix design creativity with tech — offering concept art, UI/UX, 2D/3D visuals & animations, plus full-game dev support. Their strength seems to be being able to plug in wherever you need: help with visuals, build from scratch, or do something hybrid. With a decent track record (~65+ clients, 100+ shipped titles) they look reliable.
