Powerful.
You really do justice to Ganondorf's dark, intimidating disposition. Lovin' the level of detail you used here, from the fine chain holding up the medallion on his forehead, to the cold stare paired with glowing red eyes. I'm actually really hoping that you're planning on releasing some big top secret project in 2013..!! xD
Now, this is totally my own humble opinion, so don't take this the wrong way, but one thing that seems to catch my eye in a negative way, is the roundness of his facial features, and/or lack of sharp, masculine characteristics (e.x: stubble). What I'm trying to say, is that he almost has a 'pouty' expression on his face. ...But that's just lil' old me!!
I can't draw big scary dudes for the life of me, so as far as I'm concerned, this is better than I could do! xD
