the green border is distracting. something slightly rougher, if you must use a border, might have fit better with the rough/used appearance of the stereo. also, having the lights be the only color in the image gives it a nice black and white feel. the border takes that away.
i did something similar to this I was wondering how many would pick up on it. nice pic and i like the way u chose an old system rather than a nice new one.. good job
