I cannot believe no one has commented of this yet. This is a pretty good wall! I'm assuming the background is a stock photo, I like the graffiti style look to this. A theme not often, if ever used in connection with the Homunculi. The image of lust is indeed a good one.
The wall is not without its flaws though. I'm afraid that it's a little grainy in the background, and the edge of the scan is very rough. But its still a nice wall. Just work on cleaning it up a bit.
