Not a cover but...

Not the actual cover ( probably) just what happens if you leave a graphic designer alone with some art art and inspiration.

The art piece is by Dean Spencer. Who has done numerous pieces of TRPG stock art. Normally we use stock art for layout mock ups and inspiration prior to kickstarting a project and comissioning our own. But honestly Dean's work is so good I wouldn't be surprised if some of it made it into the final version.
