I don't have any knowledge of 3D, but this was still extremely helpful for me as a 2D artist! I primarily paint people and struggle a lot with environments - both from a technical skill perspective, and from an enjoyment perspective as well, I simply find it all painful. This made the process so much more clear, the ideation/inspiration + sketching step was a key learning. I need to have a more intentional, researched process for environments. As a bonus I also got a great intro for how useful 3D is and how it can be combined with 2D techniques. It's always great to learn from a working artist in the industry!
