Answer: Hello and thank you for asking this question. I will be happy to help. Adding dept in your art is like adding more detail to make a look more realistic. Creating the illusion of three-dimensional space on a two-dimensional surface is called portraying depth in art. Many techniques can be used by artists to create depth in their compositions, some of which are simple and some of which are more complex. As a artist myself I try to pride myself in my work and add as much depth as I feel like it. You are your own artist and can make your art however you want.
Explanation: Thank you have a good day!
