damn 'photographer', you are a real douchebag. i would say that the best 'constructive criticizime' you have recieved so far is to realize that and not be such an asshole. you start a thread asking for insight and all you do is rebuke the advice you've already been given.
anyway, i like the first boot the most, but even that isn't a great photo, so please, get off the fucking ego-trip.
