Hey! Awesome illustration! So cute! :D I don't have too much to add. I'd suggest some minor things. Increase the warm light a bit more, it makes it feel more cozy (IMO). And I'd refine some areas just a bit more. Like the suggest a bit of fur on the darkest areas to let the viewer guess the rest of the part of the cat. Also, refining just a bit more the shape of the head on the darker area would help IMO. Hope this helps :)
