Previously when submitting art you could choose from 5 different comment levels and the option was hidden in "additional info".
Since our new focus for PaperDemon is about self improvement, requesting a critique is an important part of improving. So I've revised this option to be a simple checkbox (rather than choosing from 5 options) and it's no longer buried under the "additional info" button. If you check the box, you're art will say you've requested a critique. Soon I'll make the artwork requesting critique at the top of the art page.
Let me know if you have any questions about this change.
UPDATE Aug 27
After releasing this change, it turned out it had a bug preventing members from submitting new art submissions. The bug is now squashed. Please report any bugs that you may come across and I'll get those fixed.
