If its a collaborative piece, can you Co-Author yet for the Art Portal? I feel like its a great idea to get some collab stuff in there, always comes out interesting seeing the work of two people over one.
As for this 4 quarter face thingy, sounds fantastic, ill make sure to do one! Best part about making individual quarters is you can use the same 1/4 later on to possibly match better with 3 others, to find the best possible 4/4 outcome, I foresee great success.
