Do you do any post? I only ask because the photos seem a bit flat in color.
When doing portraits, be mindful of hands. Especially when putting them close to the face. A good portrait makes a person look good as well as looking natural. The hand in the second photo is a bit unnatural feeling, as if she wasn't sure where to put it and just decided to put it on her cheek.
If you are thinking about doing more in the future, I would recommend you invest in a reflector to start. That will help with shooting outside. Getting the exposure of the person to better match the exposure of the scene.
But for your first, they aren't a bad start. Keep practicing. Grab a couple of friends and test your shots on them more before going out and working with people that aren't friends.
