Recently I read some religious books and they do affect me in creating art works, Devils’ Banquet is the most representative work of them. You can see the falling angles ( or faeries, ghosts… whatever you call them) are dancing and spinning upward to some invisible SOMETHING who or which dominates all these evil existences.
To create the dark and religious moody, I tried some different color palettes, and finally the red and black is more Hellish than others, this combination is the symbol colors of hell.
