Very good job. The fashion comes out nicely, which is the main thing here.
A minor thing: the color of the fingers and the palms of the hands has too much magenta (in number 4 and the rest of the pictures of this model). I know that probably the color is realistic but still I would warm it up. Cheers,
For some odd reason, the BG looks odd to me. Maybe brighten or whiten it a bit to remove the shadows? The models and clothes look great, and are well exposed. Overall very nice.
Looks great. Except for the big wrinkle in the shirt in number 3. It sticks out like a sore thumb over her chest area. Number 11 Id crop up a bit from the bottom to get rid of the odd piece of the garment showing. Or clone it out.
