When I drew this, I did it out of inspiration from a pic I saw in a slide show video thing on YouTube with Death Note pics. The one that inspired this was or Light and Mikami, I can't remember much of the details though, but I do remember the wing, pose, and window shape being inspired by it.

As for the apple... I was bored and drew an apple in the middle of working on this. I didn't want to erase it, so I put it on the window sill. I suppose it could be because that's where Seth found his Death Note, on a window sill. Though, his shinigami, Kee, doesn't care for apples unless they have caramel on them, so it doesn't quite work =-= But it still looked good at the time :D
