Vader

My first actual Star Wars fan art. Obviously, it's Darth Vader with his lightsaber.

The saber is my own work, but I manipulated a picture of vader to fit. Probably not completed, but I couldn't think of anythign else to do, so I thought I'd submit it and see if I got any suggestions. ^^

Oh, and for reference, this is the picture I used for Vader. Here

I changed a lot of things, as you can see. I did this out of boredom one night, but I would love for some suggestions as to how to complete it or what to change to make it better. ^^
