I've found in a few instances that I may admire a piece of art from what I call a "technical" perspective, IE: the colors are good, the lighting is well done, camera angles are working for the piece and the people are well done, but not care for the actual content. My best example is music. There are performers who's music or style I don't care for, but I can acknowledge that they are talented musicians/singers. If I see a piece of art that is technially good, but I don't care for the content, I usually refrain from comment because I can offer nothing constructive. OTOH, when I see something that has content I like, but feel that maybe better lighting would help it or a change of color or body angle would help, I'll chime in. I also try to point out that it's my opinion/perspective, which usually means, take it for what it's worth. For the most part, I try to only comment on the pieces that I like because of the fact that I'm not a great artist and still learning a lot about the programs and art itself. I really don't feel I have the right to criticize. IMHO, the person who's post was removed was offering nothing useful and it was appropriate to remove it. It implied something that wasn't there and it was totally uncalled for.
