First Impression:
Nice B&W. Interesting motion blur. What are those lines on the fingers?
Composition:
Found the pic too dark. Too much negative space. (After reviewing your site, I see this is your style) Interesting capture with the bottom right corner of the guitar in motion, but the top left was steady. Don’t know if it would have looked better if only the strings and the fingers were in blur.
It wasn’t until after I took a good second look, that I realized what the lines were on the fingers. Neat capture!
Subject:
I think the picture would appeal to a limited audience. The darkness and blur would also limit the appeal.
I think you captured what you wanted to! I like the detail in the steady fingers. I like the detail in the non-motion area. It works well with the blurred areas.
Technical:
Can’t say a lot technically. The lighting & DOF work for you. I also don’t think you have a lot of options with the camera you used.
Suggestions:
More of the neck, to the right may have reduced the negative space. (Not sure of the proper name)
Summary:
Interesting picture, technically ok, but not a subject or a capture to evoke a WOW from the majority of the voters in this “Best of 2005” challenge.
I like the negative space, though I think perhaps you've gone a little too far, and I don't like the effect across his fingers generally, buy nice composition and depth of field save this one 6/10
More of the Bass? different position of the hand playing? There is something missing, just can´t tell you exactly what would have been better to make this image special..
