Hmm, not bad...
I'm going to be very critical in this review, just to let you know.
Alright, for one thing, you overused the blur on his pants and the shine mark makes him look strangely disproportional, as if the front of his thighs have a lot of padding.
The snowboard strangely reminds me of a Christmas stocking for some reason, try for more of a half a circle shape next time.
All in all, not a bad pic, he's rather cute, personally, and the shading is pretty good too. Good pose, he looks fairly natural like that.
I'll give it a 7/10. Not exactly fantastic, but it has potential.
