I agree with Chernabogue on the time, a month should be more than enough time to complete any entries. But for my end id like to see the contests being with non midi based instruments, at least for things other than drums. I can make some really nice sounding symphony with my plugins and midi, but for a contest I think it should be just physical instruments with again the exception being drums lol. As for themes I think certain groups would be cool, like as in this month is forest month, next month castle keep month etc to broaden the scope so that not all entries come from the same game. But then again, entries from the same game would be pretty cool actually to compare against the competitors lol.
