So Mike Mignola did not actually create this image, but the interpretation of his art style is so damn convincing that one might think he did.
On a slightly related note, have you ever seen the following 3D Hellboy demo?
I’m not usually a proponent of 3D over 2D animation, but this is how the Hellboy animated movies should have looked. Maybe they could utilize this art direction and repackage The Amazing Screw-On Head more cost effectively. The Amazing Screw-On Head was awesome.
