If you really wanted to put each pixel in it's place, then yes, you could. But the idea behind an MS Paint contest is that you take a blank sheet and use basic tools like the pencil, spray can and bucket fill and draw with those. If you've ever played iSketch, that's the general idea.

Looks like we have a decent sign-up so far. I'll be closing sign-ups and starting the contest within the next 48 hours. And I'll send reminder PMs to everyone that signed up too.
