Just found out that Adam Hughes has a new DVD out called 'Drawing Good Girls'. It's a 80-min DVD. He goes through his process, draws a pin-up illustration from start to finish, and demonstrates how he uses Copic markers for his art.
There are a couple of promotional videos on Youtube that I found. And that's his artbook Cover Run clipped at the top of his drawing board.
This is the trailer.
