I see what you're trying to do here, but the extra stuff in foreground is begging for attention, drawing me from the musician. I wonder how it would be without the musician.
Wow, plenty to look at here. I'm loving the color contrast, really makes the back room come alive. I guessing- did you gel the light in the back room and selectively desaturate other colors?
Thought it was too busy, until I began to actually look at the walls. Got some neat paraphernalia captured in the image. Still, it does overwhelm your main subject, if it is the person playing the guitar.
