Hi Astin
I think the model looks great and you have captured her well despite the simple/cluttered location.
For #1, there seems to be a HALO effect around her. The tone is lighter than the rest of the photo.
For #2, i agree that the pose is great but it seems a bit strange as her shoes has not backheels! It will be more rational if she's holding the backheel i think.
For #3, i just don;t quite like the tree behind it. I would probably take a closer photo as it's quite a dull day as well.
Just my 2 cents worth!
Cheers
