This is brilliant it really is. If you just glanced at it you would this is was a really nice illustration that shows two men meeting up for a fight. One is built like the proverbial brick shithouse and cheered on by his well-to-do fans, whilst the other is a lot smaller and... wait a minute is that tail he's sporting there? This changes everything!
This is the kinda work I would love on my office wall. I love that the artist hasn't gone too over the top with the devil's look. He's a little bit shadowy, has a cap on to probably hide his horns and his car is most definitely of the sort I'd imagine the devil to drive.
There's a few more amazing illustrations by the very talented E.Korsgaard over at Artstation.com
