Well your picture looks great! I can see that your beautiful. A lot of times people look at the quality of the pictures and judge the model on creativity and style.
Honestly the last thing they care about is how good you look. A majority of Runway models are NOT very attrctive in person. The want to know about experience and talent. For a new person it can be like trying to get your first credit card from a company that requires you have credit history.
