Agreed! This is an incredible painting!
I love Hercules! He's an amazing mythological public domain character! I've been a fan of the vast majority of the different takes on Hercules. There have been a few I didn't appreciate and like such as the Lou Ferrigno-Hercules, the Kellan Lutz-Hercules and the DC Comics version of Hercules(who is a villain).
That's so awesome scene. Lion mask is really stunning and it's absolutely great idea to give scary impression to your enemy. His mimic also shows great warrior never hesitate never fear
