This is a good idea, and would have been a good image if you had the proper equipment, you need to back off with your cammera until the image is in foucus and then crop down to what you want, or you need to invest in a macro lense, which will enable you to get this close to your subject.
It's not very sharp, is it? I'm wondering what the opposites are supposed to be: the black and white keys (I'm guessing that the picture is a close-up of a piano), or the black and white colors visible on these black keys. IMO this shot would have gained a lot had you zoomed out a bit and got a wider shot of a few keys.
Hard to tell what it was at first glance - now I see it's paino keys. Nice attempt - would have preferred it in focus, more contrast. The composition would have been GREAT! Nice try...
I don't understand why the shot is so blurry. And I think the balance of white abd black keys needs to be better to work for the opposites theme. Keep at it!
If this was in focus and the end of the keys weren't blown out with light this would probably rate an 8 or above, I like the crop and the composition of the shot but the other factors hurt it a great deal. A 3
Nice, wish you could have got the focus though! You might have meant to do it this way though, but my opinion differs I guess. I think if you rework your photo you could have a winning one here... (I'm jealous!)
