I really like your concept here. I find the expressions on both subjects to be very natural and evocative of "Intimacy". I would prefer a tighter crop on the faces and to see the tops pf their heads.
I really like this one. You've given us a glimpse of a private and meaningful moment. BTW - it's hard to tell from the limited resolution image, but it looks like the guitar is strung for a right-handed player (conventionally, the thicker strings are on top).
I wish we could see all of their heads... and their faces were as lightly lit as the guitar. As it is, my eye goes right to the guitar and I have to pull it away to try to explore the rest of the image. Good feeling photo... just would benefit with better lighting and composition, I think.
I could see this up in my room poster-size, great capture of intimacy. Only improvements I could see would be either more or less motion blur on the hands, no flash reflection on the bottom of the guitar, or a little extra space on the left so that the end of the guitar isn't "kissing" the edge of the frame. One of my favorites.
