COMPOSITION
I think you have placed the subject(s) in the frame well. You have avoided "centering" them, and have set them at a dramatic angle. I do think, that cropping the control key similarily to the microsoft key would make it seem more balanced, maybe. Perhaps including a bit more of the bottom of the keyboard would be more effective as well.
TECHNIQUE
I think the lighting and focus work well here. There does seem to be a bit of glare, so maybe diffusing the light with a thin cloth or tissue, if you don't have a diffuser, might work. Otherwise, there is not a lot you can do. It seems a small thing, and nit-picky, but the hair/lint does detract a little. Noticing details like that can really help, especially on sites like this.
OVERALL EFFECT
Personally, though the technique and composition make this a relatively strong picture, it doesn't pull a lot of emotional appeal, I think. It met the challenge well, and it was something that was familiar to all of us, maybe too familiar. I think you needed something "extra" to set yours above the rest. You also suffered from the fact that there were other keyboard pictures, and that, unfortunately, is not your fault. Maybe if you could have added something to make yours even more unique, more viewers would have liked it more. Again, it is a well taken photograph, and meets the challenge well.
