You will score low for two reasons.
1. Blurry photo. No details can be made out.
2. The min isnt based.
I think this may score a six if you fix both these problems
I think there is an 8 hidden under the blur. From what I can tell the painting looks nice :)
Google camera macro settings, and see what you find, or look on the forums on this site. Sharp photos can mean the difference between a 4 and 8 on here. I think this will be a good example.
