shot 1 - i like the contrast but the color saturation is a little much to me.
the black and whites are decent. maybe I've been shootin too much technicaly shit, but they lack anything interesting to my eye. and you may want to use unsharp mask to bring more sharpness in
for the love of god don't shoot pictures like this, they are bad. no offense but photographs like this irritate me because they aren't interesting.
the picture of the girl looking into the window is pretty cool, you should brig in a flash or dodge her using a layer mask or something because it's cool.
overall they are decent shots, but lack something really interesting, not baqd for an amatuer however.
