It's simply money that has been positioned and photographed. It shows very little knowledge of photography i.e. control of lighting (too much flash -- difuse your flash or use natural lighting), depth of focus, use of shadow and reflections, compostion (everything is centered vertically -- try just throwing the money down with one crumpled and then shoot it from 10 different angles). The choice of subject is rather boring, but that isn't against the rules. READ //www.dpchallenge.com/tutorial.php?TUTORIAL_ID=33 about literal artwork.
what's rare on this photo that makes your collection special. also I does not like composition and color cast. Even if I do not know you I think you can do it better 2
