Hi Matthijs! i like your goal, when i was in highschool i dream to be a filmmaker, but when I realized how much it is hardly feasible task, I decided to give up and find something that is right for me. I can give u only 1 advice for now, register on steem.slack.com and talk to big whales, take an interview from them, it will help you to make right decisions while filmmaking ur project. I'd watched your work "Dio - We Zijn Hier ft. Jayh" u have great skills i must say, im 100% sure u will have big success here too!
