This was a self portrait image I completed a few days ago for my AP 2D Design class.  I love the humor of the game Portal made by Valve; I decided it would be pretty cool to insert myself into a test chamber similar to the ones experienced in the game.  Everything except the walls (I copied those off the internet) I created from scratch using vector and raster tools in Adobe Photoshop.  I was even able to replicate the Aperture Science logo pretty accurately by just using the pen tool.
