This is my latest personal piece, I had so much fun with this one. I started building the environment on Sketchup to get the overall measurements right, then I worked the rest of it in Blender. I used some of Quixel and Textures.com for surfacing. I rendered using Cycles with passes and then painted over in Photoshop
The lighting was inspired by the work of cinematographer Lawrence Sher on The Joker. Additional reference was the work of Silvia Mingolla.
