Looks cool, love the colour scheme.

Just one thing, have you ever experimented with media outside of a computer and a tablet? Like, graphite, charcoal, wax pencils, etc.? I think you might find it'll open you up to a lot of different styles.

Lately I've been getting into still life and life drawing with wax and graphite pencils and it's fairly awesome. I also recently bought a bunch of architect books for technical and perspective drawing that I am dying to get into.

I dunno, just that I see a lot of your stuff (while it is awesome) is all the same. Be nice to see you experiment, and see where you go from there.
