I`m not the competent person to judge you but there`s something wrong with perspective, I mean that in the bottom shells seem to fall down the screen like if the were dropping down from a conveyor... also shadows look too sharp for me, I guess there was only one source of light in this piece? Maybe you could put some identification on the butts of them like " + .45 MAGNUM + MADE IN U.S.A. ".
must have took you aa lot of time placing those stingy fellas and a nice hardware too I suppose - anyway I loved the concept and the picture itself, well done sir!
