Procrastination?

Well exam revision isn't being the best thing ever, but wh'ev. I hope it goes ok anyway.
I still can't really write anything exiting, so have some concept art instead. Don't worry, I didn't do it all today instead of revising. It's been sitting around for a while. (well sheet the third was from today's sesh.) Hopefully it will make it past the concept stage sometime soon, but you should know better than to trust me when I talk about finishing creative things. Can you guess who's who?
