sXe

I'm trying something new. Was looking at some of my old scrappy graffiti pieces i do on train journeys, as the same time i was on the sXe page here.
Figured i'd try do a wallpaper for them, this was adapted from a thing i did as a laugh for a friend, it'll be part of the design of the wallpaper if people think it's ok.
I'm either going to do it all b+w - unless i figure out how to use PS and choose a good colour scheme.

Opinions and advice please.

There's also a black framed version in my scraps. I don't know what else to do with it, but it's sure not how i want it yet!
