I like how the lights were set up. In the first round, I gave this a 6 because of the background mostly. But it did make an impression so I have come back to bump it up. Good job.
Nice lighting in this. The texture of the wall is cool too. Maybe cropping out some of the overexposed left side would give the shot an interesting feel. I think that with the silhouette left of center, and the guitar neck crossing over the center to the right side would give an interesting balance.
No failure here. Centering the subject is rare now and seeing this is refreshing. After 30 years, I am still teaching myself the guitar and have learned not to give up.
