I'm really pleased with it and it made me reflect on the other covers I've done. I definitely think I'm getting better at it. 'The Doorbell' one isn't great but I really like those for 'Dear Suzanna' and 'Camera/Phone v1'.
Anyway, the purpose of this post is purely and simply to post a little gallery. Hope you enjoy it.
Update 4th July 2012: Added the covers for Camera/Phone v2 and the first two Guillotine! stories
