Agreed...I thought mischief...even though black & white, I think that saturating this strongly and increasing the light (maybe a little increase in the contrast) could have improved the strength of the image. I would personally like it a little brighter. :)
This a nice portrait but the blacks and whites are non-existent. It may be what you were going for, I don't know, but I would add some contrast to this image a little bit.
