it's a really cool picture. I really like the 4 frame where he's sitting after getting free.
but personally I don't like these overly bulky guys, in the frame where he's cutting himself free his' shoulders and back just looks like a mess of bulks.. not to mention his ass is bigger than the cat....
I feel terrible for pointing this out, and I am really sorry to do so (I know I know...if you cant say anything nice don't say anything at all) but keep in mind this is just personal preference
In the fourth panel he's meant to be standing but since you can't see all of his legs he could be sitting as well, about the big ass is because i tried to make foreshortening seen from below but then again i should have made the cat bigger as well so you're right, i don't agree about the mess of bulks though because i drawn each muscle at its place not just random.
like I said it's not your drawing in perticular, it's that style of overly bulky I dont like, I didnt say you had messed up with it only that I didnt like the style, and as said it's a matter of taste and I know it
and sorry I meant the one where he is kneeling, rubbing his hand
