I rarely browse the galleries, and when I do I rarely comment. When I do comment it's because the image evoked some kind of feelings/thoughts within me and I felt compelled to let the artist know.

Routinely if I don't like an image, rather than hurt someone's feelings I just close the image and go onto the next one.

Many people here will ask for help on an image if they are struggling with it, but I am of the belief that the gallery is a place to showcase your finished work. So with that in mind, who am I to tell the artist that they should have used hues of blue instead of green?! Or that the lamp should be on the left instead of the right in order to provide balance to the image?  I figure if they wanted to use blues or have the lamp on the left they would have done that. It's their image and their vision, not mine.

Now if someone specificially asks for helpful criticism, then I'll do my best to tell them what works for me and what doesn't.  Does that mean their image is bad? No. It just means that if I had done that image I would have done something different in it, according to "my" vision.

Now on the other hand if I see it's a new Poser user with one or two images in their gallery, I will tell them that they are off to a good start and then gently give them some suggestions on ways to improve their "concept" via lighting or scaling.

I frequently send a link to an image I'm working on to a few people via Site Mail to get their input on how it's looking and any tips for improvement.  I also have been running it by a couple people at home too, just to get "non professional" opinions on what they think and what they feel could be improved.

"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
