i agree that certain techniques are learned over time. and some have a better innate sense of what just works right than others. yet, i feel that it is a shame for a piece to get 60 "oh wow" comments, and nairy a one letting them know that their shadows are all wrong, their joints need fixing, or, they might need to turn down their diffusion. they learn nothing from that. at least if someone did comment in a way that was less than glowing, they might try and "go figger" how to fix it and do better the next time. and, since some folks do know how to do the technical aspects of art, shouldn't there be a type of 20 for that? the 20 is supposed to be the best of the site, here. yet, it pretty much is simply a popularity contest. (no sour grapes, either....i have made the 20 on more than one occasion, and in more than one gallery. i'd just like to see it get much better.)
