2nd tag is awesome man, first is cool, though i feel the stock needs to fit in a little more with the background effects and colours. By maybe making the blues on him, a little more redish, also, the thing on his glasses, and a tiny bit behind his ear, i dont really like, I dont know if its a reflection of something on his glasses or u did it yourself, but it'd look better, with just highlight effects on the glases, because they always seem to look really cool when made high quality.
last one is my favorite I have seen from you I looove it great fx and lighiting jusrt make focal a bit more clear
