This is a good guitar shot. That glare spot which is front and center is not good. I wish I could say how to contend with that. I need to learn myself and will come back to see other comments.
Nicely done. The only criticism I have is the little bit of the label that's visible in the body cavity - would have been nice if the hole were darker so that you couldn't see it. Tough to do under basic editing rules, though.
