Sorry, but I think this is just a bad, uninspired shot. It's almost as though you quite literally just read the title of the challenge, picked up your digital camera, and snapped the first photo you could think of that would work with the theme. The colors are terribly weak, the composition is boring, the actual "image quality" (resolution) is poor. I'd simply recommend that you try harder next time.
Nice idea. Mirror has lost you some contrast and maybe sharpness. Sharper with more contrast would be better - post process to sharpen and recover the contrast.
