I don't know how far I'll be taking this, but I've started trying to teach myself some Photoshop stuff by doing a run-of-the-mill "shameless recoloring of video game sprites" project.
I've picked out characters that I think I'm going to use for each duder, and started working on Patrick and Jeff. I'm fairly new to pixel art, so I'm open to suggestions.
*Edit, most recent version: I think I'm going to put this project on the back burner for now. I'll probably continue to work on it now and again, but not with enough regularity that I feel warrants or deserves update posts. When/if I make some significant progress, I think I'll just start a new thread (besides, some of the thumbnails seem to have broken in this thread since the relaunch).
