I must agree with crystleclear, the picture just is a bit out of focus. As far as constructive criticism for this point, just take the shot again, perhaps with a tripod to keep the camera completely steady.

As far as lighting, the picture is too dark; it could use stronger lighting. The angle of the light is excellent though, and I love the coloured shadows. The object itself is just lost to darkness and blur.

Flawless. The subject matter, the lighting, the effect..... This is an incredible shot.

I'm sad to see that your image did not win this contest, beautiful shot.

Works surprisingly well. Simple, yet easily recognizable.

Nice job on the image! Although, It would be nice to see more creativity than just using the example given in the Theme's goal. The cheese grater addition was a very nice touch! Looks great!
