A Prize For Guessing What This Is!

every now and again, i like to use a silhouette of my work to see how well-balanced the image is. it's not always necessary, but in this case it was, and I'm pretty pleased with the results! can you guess what it is before i post the finished piece? the correct or closest answer will get a free caricature that you can use for your Facebook or Twitter profile picture (like mine on the right there!)
