Just a thought on sizing... This contest looks like it's going to be BIG and attract a LOT of attention. The winner, therefore, can surely expect his art to be displayed in some shape or form, and that (correct me if I'm wrong) will probably include print - if only from magazines that may cover the contest, but maybe posters too. With this in mind, isn't there a requirement to render to print dimensions, say around 5000 x 3500? After all, if someone decides to submit a 600 x 600 it's never going to get print exposure anywhere! It's way too small. So should there be guidelines on this? BTW - I'm not suggesting the SUBMITTED version be 5000 x 3500 or whatever, but shouldn't there be a "for-print" CMYK lurking in the background "just in case"??? ;)
