I've had it for a long time. ^^; I get so few asks that I have to stagger them (the fanart I post is just filler) and then I have computer problems...it's lovely.
I have a head cannon that Deryn didn't always wear trousers, even if she didn't like them. Whenever I draw her in a dress, it's almost always some sort of blue, which may be because it's the colour of the sky.
