Favourite main characters

Here's a drawing of my favourite main characters from books and things:
On the left, Harry Potter. I can't draw him when he's older so he's about ten or eleven in this.
Deryn Sharp, the girl disguised as a boy from the Leviathan series by Scott Westerfeld
Aubrey Fitzwilliam, the extremely magically talented and clever wizard from the Laws of Magic series by Michael Pryor
And Gerald Dunwoody, the VERY VERY VERY POWERFULLY TALENTED magician from the Roge Agent series by K.E. Mills.
I've had these sitting on my desk for quite a while, so I thought it was time to upload them.
Enjoy!
