Technical: Good focus and colour. Looks very slightly out of focus top-right?
Meets challenge: Yes
Overall impression: Well executed, may be very slightly uninteresting.

I like the 'hard' subject choice. I do like how you have done this, would love to see it pushed a little more in post processing, i.e. darken it , more contrast. Kind of shot would be fun to play with. good work.
This is a great abstract shot. It's also a great example of a shot that should be converted to black and white. The colour noise in the shot is vary apparent and would be removed by a conversion. It's also begging for a border, but that's just my preference.
