I think the cat itself looks nice, but the position s/he's in looks a bit uncomfortable. Perhaps having him/her's front lean a bit more forward. Bend his/her legs a bit.
Kind of like the visual crit. I'm sorry it's not the greatest. I did it in Paint. But something along those lines, maybe? I don't know a lot about kitty anatomy, but maybe that will make your cat look a little more natural.
Oooh, wait. I know what I did. Okay, this one should work.
I guess I see what you mean... It helped ) thank you
