Style Study

I noticed that an artist I like (Sinix - http://www.youtube.com/watch?v=cYRJYIWrOWs) did a tutorial in this sort of fashion so I decided to try and follow along and do some experimenting of my own. I gathered a few recent sketches and made some new ones so that I could just paint when I get home from work. So far I got two done, and I'm stil deciding which one to do next. I've grown tired of the guy in the middle and I plan to change the drawing.
