I just have to comment. Great looking work you have, wicked cool.
Your pencil stuff is fantastic; I really like it, and it's cool to see you transfer some of that to digi. For the digis, work more on making hard edges harder, because there's a lot of soft. Try to use less dodge and burn and pick your own colors. This gives you practice with picking highlight/shadow colors rather than getting lazy and using that mode overmuch.
