I try to post constructive comments. Most people spot incorrect exposure/focus, fewer seem to consider framing/cropping. For most amateurs (myself included) most photos are snapshots with little time for achieving perfect framing on location. Who cares? Crop it when you get back home. Don't be ashamed. Would you rather get compliments on a well framed photo or proudly say your flawed masterpiece is untouched by Photoshop? In the digital medium, it costs nothing to try different crops. Basic rule for me is: Is it relevant? No? Then crop it out! Is it uninteresting? Yes? Crop it out!
