I actually like the black and white ones you have, which is odd because I usually don't like black and white very much. I just didn't dig the first two, the first one her eyes are too green to the point where you know its edited, the second one is too posed, unnatural.. Just some constructive criticism.
hmmm.....tempting to use as my background? Very nice photography. Yeah, I like the b/w girl w/ camera! I couldn't really tell but was that metronome a Seth Thomas?
