Acquiring game assets

I'm a programmer, so the art that I make in games is normally only used as a placeholder.  The games look a lot better once some better quality art is in place.

The first thing this game would need is the background for a level select screen.  After a couple of hours of searching, I settled on this one:

I would need to use my editing program to stitch a few copies together, but after dropping it into the game I liked the way it looked.
