A great start to 2018 and spend less $.
Headshots are expensive. I get it. So if you do not have the funds for new ones today, go to your last headshot session and pull out one or two shots you liked but did not pick. Yes, you have to pay a little to put them up on the casting sites, but it is far less than a totally new session.
Let your agent know that they have something fresh to use on submissions.
