Still what Bab said. The arms should be thicker, or make the legs thinner.
I'll finish the bigger one eventually.
He's going to be holding a shield in his right hand, obviously the sword is just a placeholder.
Ofcourse, not going for omg anatomically correct since it's smaller and harder to show detail with a proportionate head.
That. Is. Hot. I would just change making his pants look so fleshy and you're golden.
He looks off-balance. His legs need to be stable and contracted. His limbs are quite arcked (is that how you spell it? :s) and his hands seem quite small.
Concentrate on the stable stance for now though, as you're not going for "omg anatomically correct".
It looks like he has two different legs. The left one looks taller, the right one looks thicker.
