I have noticed that many of the comments on Caedes are nice and polite, but most of the time, not too helpful or criticizng. I appreciate all of the nice comments I get, but it would be nice to get some criticism. So here is my idea:
Instead of having that one comment box for an image, there would be two:
Pros: (text box)
Cons: (text box)
I think this would encourage constructive criticism and give artists more accurate feedback.
