His left forearm is still a bit wonky. All of his muscle is contained in one little ball up by his elbow when it should be more spread out. And I don't think that little V thing between his pecs and abs should be so defined, but whatever. And I'd make his ass stick out more, since I would think a man that muscular wouldn't be have one built like a frog's.
Also his pelvis his huge for a pelvis (just an observation) and he has no ears. Or really tiny ears. Or feathers for ears. I don't even know.
Hmmm ~ the only thing I see that is a little funky is his left pec, which might be a little too curvy? :0 Mana in the last pic you did also had one curvy side. =3= <3 Waist, abs, and arms look delicious and fine. XD
