A good use of transparency and focusing the light on the foreground. My only suggestion would be to have the back of the die in sharp focus. If the whole lighted part were starkly, sharply in focus this picture would have been a 9.
Good composition and a nice job on lighting the cube, however, the focus is really a bit too soft and brightness in front shows too much of the texture from the backdrop.
The concept on this photo is excellent. In my personal preference, I don't care for single subject photos where the subject is bullseye centered in the frame. The focus is a little too soft in this photo as well... = 5 - jmsetzler
