Those kiddos are ADORABLE!!!! Perfect little models!
My opinion, I like them all, the 2nd is my fav.
The 1st one, great shot, but on my computer, her little face looks more on the greenish side and seems too dark. Everyones pc monitor will be diff. but I think it you were to use your curves or even brightness with contrast up, in your editing software, you could make her face more brightened. It is still good though. Pict #4 is a little bit blurry, should be an easy fix with editing software.
You have a great eye for getting a good shot! I wouldn't hesitate using these pictures for your site!
How long does it take to get picts back from photographers? My dd's friend is a photographer, she told me she would take pictures for products. BUT she doesn't have her in doors studio set up, she mostly does outside shots, but she is good and has a nice camera.
