I just looked at the notice on the critique system, and I can sum up my thoughts in three short words:

What the fuck!?


Why should artists submit their works to a site that wants money for the ability to receive critiques on your work? The current comment system is good enough, I guess, but when there's a system for the specific purpose of critiquing art, and people don't want to pay for such a thing, many are not going to think of dropping a critique comment...

Those are my thoughts anyway.
