Voted earlier leaving comments now. Great silhouettes here in this shot - nice and deep to contrast with the light sky. Love the mood that this creates - the windblown hair of the person and the very identifiable shape of the guitar as the musician is strumming really creates a carefree spirit. I am trying to figure why you would make this a B&W rather than in color. With the title being "Songs of the Night" some deep blues/violets/black hues would further emphasize the look and feel. Not only would it possibly add some appealing colors but the colors themselves if cool hues (blue, purples, greens etc.) tend to influence mood. The cool colors could further invoke the carefree mood; the feelings of serenity. I would guess that the B&W is to call more attention to the singer/musician which that it does, but the connection of night and songs at night is not as strong as it could be had it been in color. Nonetheless a very cool photo - one I could easily see on an album cover.
A lot of good silhouettes this challenge. I wish the background was a little lighter. Probably would've cropped off where that dark line across the bottom too. The silhouette itself looks pretty good though.
This is one of the cooler silhouttes I have seen in a while. I love the messiness of her hair and order of the guitar. Its very easy to get sucked into this picture.
