I guess you have been playing guitar for the last 24 years. Not everyday stuff for all of us allthough it is for me.
Nice composition and lighting, the big thing on the left is not sharp enough to be recognized, what is it, a finger? Allso the shadow in the top right colour distracts the image.
I find the out of focus finger to be quite distracting. I realise the 'playing' is part of the every day thing but maybe a different composition or a less of a close-up may have helped the hand from being as intrusive. The image is also a little dark. The main problem is the composition, though.
