I do a fair bit of random sketching and drawing, though that's reduced quite a lot since I started doing this webcomic. Some of the pictures here are of characters from the story, but quite a few are just me messing about. If I get what I think is a good idea, but have no clue as to how I could make a story out of it, I usually just draw a picture. That way I get reminded every time I flick back through my sketch book, and hopefully it eventually gets used (if not, at least I got some drawing practice).
As you might expect, these are all pictures of characters and such from the comic.
And these are of whatever else I fancied drawing at the time.
This stuff is pretty ropey, but all this pictures have something about them that I like. As you may guess, they were drawn before I started on the comic properly.
