I agree with inshaala.  I am but an amatuer but I try to improve.  I'm not sure my photography skills are improving but I have grown more critical of my own shots by observing the spectacular posting in the gallery along with the poop.  You will be hard pressed to dig out the truly honest remarks from the mutual backslapping.  This goes for all the galleries at Rendo.  I have found that a few of the forums have people there who will be honest and polite both if you have a shot or scene that needs technical assistance.  Forums are a far better source for honesty than the galleries.
