add sharp line of light (the gray maybe) above the line for the glasses, or make the frame a bit darker.. can taper it off into a darker color as it reaches the hair.. maybe even skin tone to transition when on the hair... Really good color work. Nice guitar lighting. Should the top end of the guitar go up so high? I know it's bending back a bit, but it seems to raise up a little too much when there should be more foreshortening.
