So here's the in-progress pics of how I painted up this one. I worked up the background in greyscale, did all the foreground chair detailed then pushed some 'infernal' lighting in back. Then moved onto our featured demonic mistress, face first, make-up, hair and then painted in a shiny red latex dress before going for final lighting in the finished piece.
I knew from the quote that this had to feature a heavy red palette so committed to it fully on this one.
