Could have been much more, had you paid attention to the light at the window and used it to soften this. As it is, the details aren't there, and the attention to them is lacking, and so 6.
u'd fit right in around here. ok my comment is going to sound umm funny but im being blunt and honest.. your crotch is staring at the camera but your face nor your guitar is.
Overall seems soft. My eyes are drawn to the overblown light coming in through the window. The lighting does not seem to fit the mood and posture of the subject. Perhaps exposing for the window light and using a fill flash would provide a sharper result with more contrast.
