'Eavy Metal
'Eavy Metal is Games Workshop's dedicated painting studio. Their job is to paint models for codices and box-art. They are masters of thinning their paints, and they recruit from the best, like Golden Demon winners.
The only real thing worth mentioning about 'Eavy Metal was Darren Latham, then he became a sculptor, now the people's painter Niel Green is the man of the moment tbh Joe Tomaszewski. Joe. Motherfucking. Tomaszewski.
As of 2015 however, Joe has betrayed the team and turned to twiddling his thumbs as a profession. Now its all about Gary Birdlime the legendary Shraven.
The end.

It's a common mistake from those new to the hobby to try to copy the 'eavy metal painted model pictures on the box. This is pretty much a bad idea, especially if you don't understand things like "base paint", "thinning" or "drybrushing". If you have any doubts, remember: You can paint 'em however the fuck you want. Nobody begins as an 'eavy metal painter. But at least try to make sure that other people can look at the finished product without hurting themselves.
The miniatures you see on/around the boxes aren't completely 'Eavy Metal's work, Games Workshop neatens them up in Photoshop before releasing them.
