In the left mirror we have Remi Vitoux designing his superhero costume, in the right mirror, he's trying it on for the first time (or is this just the finished version of his sketch?)

Remi is holding his pencil strangely, and his sketchbook is at a funny angle - I was going to fix these things, but then it struck me that Remi was the type to draw in an unusual manner.

His hands in the left pic are Photoshop-traces of scans of my own hands (but not the cartoonier hands in the right pic.) That's my real sketchbook in both pics, though it's made to look a little bigger than it actually is.

He isn't actually taller on the right, (well, not much) the stump-boots are lifts.

I'm not entirely sure how he achieved any other physical changes between the left and right pic, such as the larger tail (it could be a fake.)
