Hi @Anonymous
Your store looks great, a few things you could add which would make it even better:
1.) Add more branding, specifically on the product page. Maybe a picture of the artist with the “GS Music Course” shown somewhere in the background or a t-shirt
2.) Social proof, this is hands down one of the best ways you can improve conversions and credibility among shoppers. Maybe get a video testimonial of some of your past clients or a picture of them learning to do music with you or something along those lines.
Hope this helps
