model test shoots for portfolio/compcard
Every area of the country has different requirements for their models portfolios. What works in Chicago doesn't work in Miami, New York, or Los Angeles.
Each is unique to the clients they serve. Miami fashion market is largely clients coming from colder climates to shoot spring and summer catalog. The south American market is huge in Miami. the local miami market continues to grow for local work, which has to reflect the marketing area.
New models wishing to work in this market need to visit the major agency websites and look at the portfolios of people working successfully in this market, and create a story board out of those looks for portfolio. Instagram isn't what you need to decide what to shoot, but it is important to show the agency who you are.
