One possible suggestion is to find a photographer who is also seeking experience. Traveling the path of discovery together will provide both of you with confidence and experience that will allow you to progress. As you both become more comfortable with eachother and focus on growing your abilities, you will start to notice a change in the results.
Just as you need to learn how to move, pose, and express yourself, photographers need to learn how to make models comfortable, and how to direct them if necessary. Experienced models should be able to react to a photographers request for an emotion, pose, or abstract suggestion.
All of these skills have to be learned through experience and continual learning.
Look for instructional material on facial expression and body language. Study other models. Try to understand what you like, what you don't like, and why. Then try to to recreate expressions and poses of the things that you like. It may sound ridiculous, but even having someone take a phone pic of you trying to recreate a look will provide you with valuable insight on how to change.
Modeling is a big world and if you don't look outside your immediate surroundings you might miss something valuable.
