The main idea was to make a render where the shadow would look like someone hanging, inspired by one of the shots from Evangelion where Gendo was sitting with a shadow that looked like a cross. The most difficult part was making the lighting, as I struggled to do moonlight lighting that fit the scene. So instead, I make the render look more like my old render, Lying Down (https://www.artstation.com/artwork/1xrWeq). The first version of the render has the character standing on white ceramic tiles. But I found this to feel too empty. So I recreated it with a terracotta texture and added a frame so the viewer knows that they're looking through a window and the shadows are from the window frame.
