A very pleasant portrait of a pretty lady.  She has a very appealing expression.  The leaning against the tree pose adds some energy and dynamic lines.  Good composition and use of space.  Good color, good lighting and modeling of her features in spite of using on-camera fill light and a low reflector.  Some photographers would think the lighting a bit flat but I see very nice diffused highlights on her cheeks, chin, and bridge of her nose so your lighting works for me.  Her facial features are a tad soft, probably due to using a large aperture to blur the background.  I am uploading a before & after sharpening for your consideration.  Nice job.

Thank you John , I appreciate your comments and I agree with the sharpening. 

very nice

I would guess that she is pleased with this, which is the #1 consideration, right? It's a pretty picture of a pretty girl.

In terms of critique: Do you think her eyes might be a little too glittery/processed looking and the facial features a little too soft/overly processed? I would perhaps adjust the contrast and sharpness of her blouse, as well.
