The photographic expansion is a beautiful thing! Good post production work. I do not think the BW makes the cut. A contest you say? If the theme is "models photographed well" you are a shoe in.
The business of models is something I know very little of. Just because you are beautiful does not mean you are going to get work. Generally I think it comes down to the drug addict, holier then thou, art director. Not to mention the schizophrenic, drug addict editors.
Good Luck!!!!!!!!!
