Pool Hall Concentration (1 Pic)

Hey everyone - just entered this in the "Concentration" challenge - was hoping for some feedback. Kind of bummed about the hand in the middle left side of the picture - I tried cropping it out but it would ruin the picture. I'm sort of new to the challenges, but would love to get better. Taken with the a55 w/50mm f1.8 using the High Contrast B+W setting. Thanks for looking.
