Constructive comments are also hard to give sometimes as this is an art site, so what may be a over exposed picture to you could very well be what the photographer intended. I have noticed some pictures that just really werent up to par with what the member had posted in the past and I had to make a comment on those pictures as he was receiving nothing but the standard "OMG what beautiful work" I looked at it and was like "what is this its out of focus and pixelated, this is terrible" now I didnt say it that way as that would not have been constructive.
