God, Kittehness, WHY MUST YOU GET EVERY POST BEFORE ME? Heh.
So, the stuff I have to add to that (which is not much considering all the stuff in the other post about wings, etc.)...
The neck of the first guy is too thick. I think the neck starts a little bit thinner in the back. My theory is such because the connection to the back of the head is really straight. Take off a couple millimetres from the back of the neck. The arms are also odd. They look sharp and skinny, but yet they're muscular and veiny. I'd say you need to make the arm less pointy and more bubbly. The torso is too thin around the abs. Now, I've had to say this on every picture I've seen with a guy showing his chest. HE NEEDS NIPPLES. I'm tired of saying that. Heh. The collarbone... bones are a little too thick (I think) and really sticking out too much. It looks like they're almost not attached to the chest. The right hand on the first picture needs work (the fingers are coming from every direction and it almost looks like they're overlapping. Both hands on the second picture need work. All of the first guy's features are pointing up without his head looking upwards. The third image has the same problem with arms as the first. Also, the head looks so square and thin that if he were to turn around, his features would all be squished on his head.
Sucks when one person tells you the anatomy is great and then the second person tears it apart? Yep.
