Take your time and learn. Designing a business card is not an easy task for a beginner like you and competition in this category is fierce. You will have more chances if you concentrate on Party Flyers category.
Try to keep the design simple.
Choose no more then 2 fonts.(Try https://fonts.google.com/specimen/Montserrat) You can play with 2 fonts from Montserrat Family. DO NOT MAKE THE TEXT JUSTIFY! EVER!
Use information hierarchy. Ask yourself “What is the most important element into your flyer?” and make it visible. Starting with that element you can create the hierarchy based on importance and visibility. For the flyer the most important elements are titles, dates, artist names. Location, contact info, price and other notice are the secondary information and you can do it less visible.
