The patterns and textures in this shot are just wonderful. I love the way the lines are all perpendicular, but don't interfere with each other. Very well composed and executed.
My only suggestion to help this out would be to try to bounce your lighting off of a white (or other semi-reflective surface) in order to minimize the glare. There's a large hot spot right in the center of the frame, and a couple of other shiny areas throughout. Bouncing light onto the subjects would result in fewer glares and more even lighting throughout.
