This is a difficult image for me to critique as there is not much I'd change here. Personally I feel that it would've even done better if the voters were more open minded that zoom blur is truly considered motion blur. Heck, it even says so in the challenge description. I like the emotion on the singers face and the upright bass player behind her is a nice touch.
As I said, there is not much I'd change for this exact shot so I'll comment, for future challenge reference, as to what might've got you a better score. Voters here really dig the color - the more the better. They need that "pop" to make them hand out high scores. If this jazz bar had some colorful neon lights behind the singer I think you would've done better. This would've added the "pop" I mentioned, plus neon lights with zoom blur are most interesting indeed.
Overall, an excellent shot that should've placed much higher in my honest opinion.
Thanks for the opportunity to critique this image Cory.
