Didn't like the perspective on that last one so I reworked it a bit:
This stuff is pretty hard to do for weird reasons - creating the masks takes forever and you run into all kinds of unforeseen problems, especially when trying to do perspective. I also don't really like the mechanical airbrushy look of them - I want to do freehand painted versions soon. Plus - I couldn't even tell you where the light source is in those last two! Sort of abstract. Hmmmmm - perspective is still off too..
