I hesitate to make comments since I am obviously not an expert, but here goes: the photo meets the challenge. I think a sharper focus and a different angle -- maybe something diagonal -- might have added interest to the subject.
To make this affective, I think at least a part of it should be in focus. Subject is not particulary interesting. I think if you are shooting a common subject, the photo has to be striking to make it work i.e. dramatic lighting or an unusual angle. Good luck.
none of the keys seem to be in focus which is disturbing (to me) because my eyes keep wanting to focus on a letter/number/character/whatever. Great idea, though!
