There should be a category for artists who want constructive criticsm to post under. I, for one, will always post under that category if there was one.

That's an interesting idea. I suppose the WIP gallery might be the place to post...but even there, you don't get much criticism.

That might be the solution, though. Separate people who want constructive criticism from those who don't. Either have a gallery just for people who welcome criticism...or just for people who don't.

I will say that I've gotten some useful criticism. It's more common in the Vue gallery than in Poser, but I've gotten some in the Poser gallery, too. However, it's not easy to carry on a conversation, so to speak, in the galleries. Since no one can reply to your comments without deleting their previous commments, and if you post a corrected image, there's no guarantee that your critics will see it, unless they've added you to their favorite artists list.
