It might be the small size of this one that is doing it in for me... I can sense that there's a good amount of interest in the photo that is just out of reach. Stuff like the reflectiveness of the phone's face coupled with the dull handset in the middle and then the dotted window in the back could make this a great photograph. But you just can't seem to see all of that at this size. That and I can only hope that the phone was bright yellow and in which case in color with a dull black, white and metalic feel to everything else a bright yellow phone would pop right out.. I have such greater hopes for this photo than what's here.
this is so small i can probably use it on my cellphone as a wallpaper without cropping. ok, sarcasm aside, what I'm trying to say is, I think a larger photo would improve your score by the folds! focus is too soft. might have tried adjusting the contrast a little.
Larger, please! I'm sure you're probably sick of hearing that. I like the concept, but perhaps a more interesting title would tell me how that is a tool of the trade, or who would use it as one.
