I have been a brick a mortar art gallery visitor for many years. I didn't feel I could give any critic of the art work there, but I could express my opinion... I just spent more time at the pieces I liked. 

Here at renderosity when I see pieces that I think need help I some times would like to give a critic. I don't. I feel that so many members might think that I am not qualified to question their creativity. I think that this feeling might be typical of the members here.  It takes a very special person to be able to teach some one. they have to both tell them what they are doing wrong and how to do it right... And at the same time boost their creativity.  A suggestion. At the beginning of  each thread place a large announcement encouraging us be kind and say whats wrong with this art.
