I dont want to interfere with the pixelpusher competition or anything but-
A few of the entries don't seem to be pixel art.
Pixel art: A form of digital art, created through the use of raster graphics software, where images are edited on the pixel level.
Some of the entries look like they used most of the brush tools in ms paint, and that isnt pixel art. I recommend you do something about it, because that isn't really following the rules is it?
