It's all original painting without reference, except for the thing that Diamond pointed out; that was the first thing I sketched to set the tone and was referenced in part from a photo found on Pinterest that actually made me shiver, though I mean to change it a bit more to make it better fit evolving ideas and story. The rest is all my own stuff made from ideas and seeing things emerge from my loose sketching process... like catching a glimpse of something in the murk of the background or the edges of a brushstroke and strengthening the idea with contrast and additional information to bring it to life.
