I like this idea. I'm hesitant to post most of the stuff I've drawn recently in the Critique Corner, and the gallery is out of the question. Even with sketches, the gallery lets users rate them. My first Saimoe entry is rated 4/10. Posting doodles would be like welcoming art block with open arms.
Still, I don't think the current setup is bad. I just need to stop being lazy and actually post some stuff.
