C&C per req:
1. Cute, but fill light was needed image right to avoid the racoom eyes. I would also try and get more level and square with the subject to avoid the skewed perspective.
2. I like the composition here, and her expression is cute, but the monochrome is a bit mid-tone rich. She's also a little too centered for my taste.
3. Great smile, but why the landscape orientation? Next time, have her turn her body slightly so that her eyes are not fully over to one side.
4. Good expsoure, but the cropped feet? Ouch! Again, she's suffering from racoon eyes, and the image needs to be leveled.
Overall, a nice set. A few minor technical issues to work on, but well shot.
Just my $00.02 worth - your mileage may vary.
