awesome event, its another skin that rises up from the pile of crap.
the changes of the face are somewhat minor, he apparantly have the same texture. you could change his eyebrows so they look like blended with the skin, for a even more realistic effect. he have a curve on his bottom cheek, while its good to definate the face some and add depth, i think you should delete half of the curve, so the darkened part remaining is the one near to the eye.
his shoulder pads are a eye candy, but i'd put some sparklings of white around the very bright areas. i noticed you mainly use burn and dodge, but its very, very important to use your color palette, that also gives a beautiful and realistic side to your work.
seems like this burn n dodge job took long enough, but dont forget to draw sometimes too, thats most likely what will make you stand above the other skinners on this website
