I really like the concept behind this. I feel like outside of just the music, in most all things a trend arrises that mimics the "old school." I too am a fan of some old school things when it comes to hippy and vintage clothing and older music, but like kids wearing 80's clothing, alot of times it's just a fad that passes soon.
Aside from that, the image itself is strong. Compositionally you did very well, but though I can't say where I'd move it, I feel like the guitar should be somewhere else. The vinyl and cords are in positions that show their form well while the guitar seems to be cut off awkwardly.
Good job overall, man! I don't know much about this style of art, but I can still respect it and tell it was done well.
