Here’s the big picture of the painting as it is right now, with loads of Prussian blue over everything except the Iron Oxide sky and the skulls.
I’m quite sure that a lot of this will change, but this was a major step forward, and adds substantial body to the skeleton, which really jumps forward again now, with the exception of the head, which will need to be touched with some Ceramic White to bring it back to the foreground.
The blue background resembles water, but I don’t think it will remain watery for very long.
