cool shots ...I gotta tell you though imho...I believe they are too dark...doesn't look like the conditions were very great to shoot...but the shadows on the first one are too harsh...they make her eyes sink in ...the second one is also dark. I'm guessing the white shirt had something to do with it...maybe threw the meter off...you might be able to recover that though in pp. hope this helped
My Comments below are not a criticism of you, your model, your talent or your skill. I offer them with a friendly tone of voice.
Image One:
Woman has relatively deep set eyes.
Light is up high above.
Use a reflector to put some light in those eye sockets.
You can carry a small 12" or so collapsible reflector with you or use a simple piece of white cardboard. Very easy and cheap fix.
Image Two:
Why is she looking at the upper corner of the image and "outside of the image?"
There are two "subjects" in this image: Woman and path. Put them together.

I Like them, she is a good looking girl and i think you have shot them well, i know about lookng into a picture etc but some time you like what you like and i like these,
I was talking about one i thought i copied that in my reply but clearly not
i seem to over use the fill flash myself but thought it may be as good a choice in that shot (#1) as a reflector - was looking for other opinions for my own knowledge
A reflector can be used without having to purchase any radio triggers etc..
It can also be held close to the face without overpowering subject (choose the right kind of reflector). Fill flash is very often "overblown" on close subjects.
Of course there are "advantages" and "disadvantages" to either method.
One needs sunlight. The other needs batteries and off camera trigger.
One is light weight and inexpensive. The other is costly and can break.
A simple piece of white cardboard (free if you search) is all you need.
