I like the idea of just starting with a character/object and then passing the work on to the next person who adds whatever they would like to add.
I personally think it would be nice if you could have the freedom to draw what you would like because we all have different strengths.
Plus, no direction will probably equal more fun. I don't want to know what's going on, I want to be able to marvel at whatever silliness or beauty or total dysfunction comes from us all working together to make something we have almost no idea about.
Well unless you are one of the last people to work on the piece, then you may have a better idea what is going on.
I am of course open to everyone’s suggestions but for me, I think we should just start drawing and see what happens.
