I’m unsure as to why time limits are such an issue…As it stands your not penalized or prevented from going over the time limit; your simply asked to post what you’ve done at the designated time limit AS WELL AS your final piece. I personally really like this, the reason being I’m no where near being considered a strong/competent digital/traditional painter, so by being able to see where everyone else is at the time limit, as well as when they’re finished with it, I am able to break it down and analyse how that persons approached the piece and then able to learn something from it.
I think if the 15/30/etc. limits were dropped it would be a blow felt by people in a similar position to myself. The only thing i think needs working on is the amount of people submitting work…but you cant really force people to pick up a graphics tab so…shrugs maybe get a little box up on the main page showing the current theme for DSF to try and entice a few more people to take a look.
Edit: And i really like the idea of the image-mash-up!! Its the sort of thing i do with friends during lectures to help get through the drier periods
