I love this more manly look for Skyward Sword Link! Love it, love it. Not that I didn't like the original design, it's just, y'know... I liked the manly, ruggedness of Ocarina of Time/Majora's Mask had going on.
And the painting! Beautifully and exquisitely done.
Incredible!!!!! My one comment on it is that this is Skyward Link we're talking about. It looks like you made his face a bit too fierce. SS Link is a more gentle boy who grew up sheltered. Though he was training to be a knight it never get's rid of the fact that Link is a care free kid who always has his head in the clouds. Literally. But all in all great job, I love it!!!
The colours are beautiful, the texture makes it look like a traditional pinting. The anatomy is very good, too as well as the pose, good job!
I think the face is improvable though, because of the eye. It looks like the eye is from a face that's looked at from the front and not almost from the side like it is in the picture. If you compare it to how you drew the mouth the eye reaches beyond the cheek bones which makes thi9s area look very broad. Your style is rather close to realism, so I think you should make the eye a little less broad and move it a bit closer to the nasal bone. But I leave that decision up to you of course.
I hope that this helps a bit and that you appreciate critique for this artwork. It's really only the eye, the other flaws I can spot are so very minor.
