This marketplace will enable different types of audiences to come together and interact with each other in different ways.

I have assumed that this marketplace will attract three types of audiences, which are:

1. Users: This type of audience will just browse the marketplace; they will neither buy nor sell any designs.
2. Buyers: This audience is looking to buy designs.
3. Designers: This audience will showcase their work and monetize their art.

The user stories for these three audiences will be as follows:

Users

Buyers

Designers
