I'm wondering, since the Critique section here seems to be more lightly frequented than artists might like, if there are other sites artists tend to submit their in-progress threadless design to in order to get additional critiques? Is there a site you submit your designs to in addition to submitting them to threadless's Critiques section?

I post designs in my deviantart gallery, and after I've gotten a sufficient amount of feedback, I move the design to my da scrapbook section.
