Nice one. But I dont like that arms, hand and the neck of the guitar are overexposed. Also the hair is little bit too bright. Contrast of the dudes face is allmost perfect. I love the light coming under the armpit and the overall tone of the picture is awesome.
First, very pleased to have your opinion here, it's always most welcome
This pic was done in order to make some sort of a test on the viewer audience and there will be an edit. I do not recall if the original have information on hands/neck, but if so, I'll try to keep it. Also perhaps I crop from right a little.
I like this one. You asked if there's any "flaws" so I'm doing my best to find any (as I am the ultimate judge of music photography ) What I would have than or at least try, I'd photoshop the mic stand off. It somewhat looks like its impaled through the guitarist head... But despite that, I love the pose, contrast and tones in this one.
