It's a beautiful piece, and I'm impressed that it was done without any manipulation. Personally, I can only play when I'm sure no one is listening, so I'm rather familiar with that sound and that feeling, and this picture captures it very well.
It kinda sux when you play and no one gives a shit to really listen. Oh well, at least I found a medium where I have found people that like to listen to some of my songs. Great image, capturing the motion and stuff.
