glad you like it
the smoke is created in Photoshop with smoke brushes I downloaded from the internet, very simple. Just google smoke brushes and you’ll find tons of them.
How the demon is composed is pretty hard to describe lots of try and error about 20 BPR render passes with different materials stacked in photoshop with different blendmodes. Total Chaos. here are two Photoshop screengrabs
and that’s more or less the base I start with. without all the different materials blended in, just the normal render passes Shadow, SSS, AO, Render, depth
hard to make a tutorial with such a intuitive workflow, sorry
