I commented on one image I think. I used "Critique Group"... I do see how that does cliquish.  I'll just leave comments and leave out the group thing.  Besides, the person says they are open to all kinds of comments, it shouldn't matter if they come from part of a group or from someone else. The important thing is the comment.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
