Initially, it was one of the homework assignments in a CG art course I took two years ago. I found this piece recently and refined it to my usual level of detail. Now I am happy to share it with you.
This time I want to do my first step in knowledge sharing — and publish the source PSD of the artwork. The file contains text commentaries inside — I've explained the creation process and marked some tips. I hope you'll enjoy it. By the way, the image was done purely in PS, so no 3D, just photobashing :) PSD file in the store — https://www.artstation.com/a/12746840
