How cool is this Vader in a bacta tank concept art?

The Art of Rogue One book is out - it features some excellent design work. This book is a visual chronicle of the Lucasfilm art department’s creation of new Star Wars worlds, characters, and newly imagined droids and vehicles.

Which is all nice and cool but given the Bacta scene in Rogue One, we feel this picture just sums things up perfectly:

It's just so simple in its ethic but wholly conveys just what Vader's body was reduced to after Obi-Wan took him apart in Revenge of the Sith.
