I do NOT use collections system.
Would NOT, either, until it is fixed to be at least a little usable. This includes:
1) Ability to add your own description.
2) Being notified of comments.
3) A guarantee that the submission will stay in collection if original is removed.

I am curious, what are folks' main pet peeves concerning art?

Top five.

Mine are... In no particular order.

• One-trick faces. Canine/feline most often. On anything that isn't.

• Same for cat/dog paws on other species.

• Stomach vaginas.

• Sideboobs (sticking to the side on back views).

• Rubber spines (pose that needs the chracter to stretch/bend/twist in a totally unrealistic way in their waist).
