My thoughts on internet modeling contests:
Many girls submit to these internet modeling competitions, thinking something great will happen after the contest, but the question you should ask yourself is:
"Who is going to care if I win this contest?"
An agency? A brand? a magazine? -The answer is no one. Just you for five minutes.
Put your effort in more productive ways and mail your photos to a modeling agency or get a headshot and submit it to a casting director. Do your homework and research. Research, trying to find the right agencies, and the real people you should be working with, is more important towards being a model, than some internet contest.
