World 3-3

So, here's the story behind this picture:

I took a photo outside of school in the forest where a pipe randomly came out of the ground, and the image file was saved as a .NEF. When I tried opening the file in GIMP, the program couldn't handle all of the information in the raw format, so it shrunk the picture until it looked like this. I showed it to one of my classmates, and I think she said that it looked a bit like an old game, that's what gave me the idea of putting a little Mario in there. It went along perfectly with the pipe. ;o

I have no idea what category to put this in! D:
