Any artists here? Show us your stuff! :)
I'll start off with something I did for my first school; a tiger that was used for printing on t-shirts:
Though it's based on a real photograph of a tiger roaring, I purposefully made it simpler because it was going to be on budget shirts. Going nuts with the detail would have hurt it in the end, I think. This is from 1994 or so.
Oh, and the original mascot was Snoopy. Dunno why they changed it after so many years.
