I mentioned this briefly to Nay but I would also like to put it out for the general public: basically, I feel like artists get a sort of second class treatment in Big Bangs since we usually have to wait until the authors have written stuff before we start illustrating... and we're illustrating for the author instead of having things written for us.

I don't have a good solution (except maybe pairing artists and authors earlier in the challenge) but I would like it to be something that is considered when the challenge is structured.
