Here is my personal scoring scale with 2 points each. The idea behind is to justify the score I gave. You have all right not to agree with it. This is just my personal opinion with whatever little photography knowledge I have. Hope it helps.
- Meets the challenge - 2 out of 2
- Lighting/Exposure - 1 out of 2
- Composition - 1 out of 2
- Concept and execution - 2 out of 2
- Over all image, WOW factor - 1 out of 2
I'm wondering why there are waves in the motion blur. Could it be that this was done with a slow movement of the hammer coming down? Nice setup and execution.
