Yes, making shorts is where and how you will learn and prefect your craft. And making a really great short will give you the best opportunity to actually make a feature. Because if it is really great, many people will see it and many will want to see you make a feature!
The film centers on a passing encounter by two people who share a charged moment. It's absolutely lovely. Extremely creative, and for me, does capture that feeling we can have when we meet that someone special.
