I vote for Dio's model...
although
that long hair thingy on the model's neck is quite narrow, hardly can become something else than a *hair*, what many kinds of skins wouldn't make use of...if only it had a face to cover the hole that may remain if the hair is made transparent
if it weren't for the unwrap, id ask the wings to be wider...but it would become crappy in the wrapping if so...
also i think that 512² is way too much, 256² would be better, also more tricky to make it look good and not taking a lot of filesize
everything else gives hundreds of possibilities, ive got an idea of what my entry will be =P
