Something I made quite a while ago though finally remembered to put it here. The reason this is so small is I wanted it to be my facebook cover photo, and you need the jpg to have pixels resized to the 8x8 compression system that jpgs use. Basically its 1/8th the size it appears on my facebook.
It works well enough, no artifacts that I've noticed.

Thanks for the comments! I remember I was working on another pulp fiction pixel art cover photo. I might try working on that again.
