some of the criteria for being finished-
First, they must be inked OR have extremely tight line work( enough to stand on its own) no erasure marks and the like.
second, color will definitely help, but not necessary- so that means these pieces should be ready for color at least.
If you are not sure that your piece isn't finished then it probably isn't. So post it in the WIP thread, and we'll decide where it should go. This thread should showcase the best of the Myth wars art, so that the casual observer doesn't have to wade through 15 pages of ideas/sketchies/doodles.
I'll add more as I think of it or someone else does
