This is amazing, the colour is amazing, the anatomy is amazing, and your sense of shading is magnificent, but I think the depth is troublesome, especially on the cat. The cat looks as if it is a cardboard cut out--extremely flat and doesn't fit well with the picture. And the overall picture is so blended together it's hard to tell what's happening.
Your art is awesome and I see much improvement in your future. Definitely going to watch you. =3
cool! great job on all the detail. every time i looked at it, i found something different. it's like one of those puzzles where you have to look for an object hidden in the pic or something. i just love it!
