Information Architecture
After doing the card sorting I made the information architecture in order to visualize the structure of the whole app.

Card Sorting
After doing the user case I did the card sorting to clarify the architecture of the app asking to an artist to order different concepts.

User case 
I wrote user stories to know more deeply the real user drawing a storyboard 

Customer Journey
After doing the benchmark I made the customer journey to understand the user process of exchanging art using post its.

First of all I made an inquiry to know if an app about art exchanging would be useful. To do it I ask different artist with online inquiries using google form.
