the second one is much better, youve got some nice aa in the face and some decent shading.
his right arm should bend more, to be more relaxed. also some parts of his arm look pretty messy
now that i look at it, both his arms have some messy shading going on.
try making more contrast on the sword, and put shadows near highlights, it brings out a metal effect
the shoes are kind of oddly shaped, but that might just be me.
nice improvement, keep it up
