An interesting entry to the challenge. The composition is good, yet I tend to think maybe a bit more off the top would have been better. The dual tonality is very nice - really sets the image out there. Lighting was perfect.
This was a really cool shot. As I scroll down to look at the image the toothed wheel actually looks like it moves. I have to give this one a 10 I am having a ball moving the picture up and down and watching the wheel turn. Your lighting was perfect to create such an optical illusion.
It may not be the way it is supposed to be, but I really want to rotate this image 90 degrees to the right. I really like the lighting on the wheels inside the case, but the rest of the lighting seems off to me.
