Great location and a good looking bike. The model is attractive, but borderline too skinny.
A few tips;
Turn down your exposure a bit. It was obviously a very sunny day. One of the most difficult things about shooting outdoors is sun and shadows. You have to be very aware of where the sun is and where you're shadows are being cast. There are light defusers/reflectors that you'll see used in professional shootings (big gray/silver discs) that are used to eliminate the shadows. Your model has distinct shadows over her eyes. I'm guessing it was between noon and 2pm? This is early morning is best for outdoor shots - great natural light and no squity eyes
Keep practicing, and experiment with the settings on your camera.
