I had the wonderful opportunity to document my processes on my latest personal project, The Hallway. I hope that it can be helpful to other artists out there. I'm still in the process of learning myself so please feel free to contact me with any additional questions. I want to give a huge thank you to Kirill Tokarev and 80 Level for reaching out to me.
