Dear Ash and Re-Magi-Nation,
I'd like to request that the rules of this contest be shifted slightly to allow the use of public domain images which are universally accessible online.
All of the concepts are possessed of an extremely unique visual style, and I think it'd add a lot to the layout and presentation of the games to be allowed to use artwork in teh game. However, not everyone is an artist or rooming with an artist, so allowing ANY art would create unfair advantages - sure.
I think allowing public domain art would be a great way of giving us extra leeway and a new creative toolkit, without dislevelling the playing field.
