I would strongly suggest that you don't become a model and subject yourself and your body to such ridicule... but if that's really your dream, go ahead. I would say your height is absolutely fine, but with that being said, I think if you become a model, you will be disappointed with your chosen career. One of my good friends became a model and her whole outlook on herself changed. She was told to pose this way, or push her chest out more like this, or stick her butt out further like this. It was as if she was no longer a person, just a picture. That wasn't who she was. She came to her senses and quit the business. Just a thought. Good luck with your career, though.
