The effect is intended to replicate a muted matte/non-specular (shiny) paint on the relatively metallic dust cover, unfortunately, the lighting in the workshop doesn't quite allow the effect to show. Once the light hits at an appropriate angle the art stands out quite noticably, but getting the appropriate angle in the workshop is another story.

ahh i see! Very cool, I enjoy the mythos collection very much! The backstories! haha. Well if this ever comes out, it's mine for sure!
