This is my first real pixel-art attempt (I did a couple of pieces for a personnal game, but I rushed them a lot). After visiting this site for a while now, I thought I'd give it a try.
I was fascinated by the Teenage Mutant Ninja Turtles when I was a little younger, so I thought it would be fun to work on a Leonardo piece. I used 19 colors including transparency, and sure I could have used a lot less but I wanted to give it more shading. I came up with the line art and I think overall it looks good.
