Our DM asked me if I wouldn't mind a bit of a spoiler regarding our Out of the Abyss campaign. He handed me this large Demogorgon miniature he wanted to be painted and fast because we  would run in to this demon pretty soon.
So the method of painting had to be dry brushing and shading, I did some details but mostly I dry brushed the miniature. Instead of following the painting guide you can find online which is displayed on the box, I went with the artwork of Demogorgon that can be found on the cover art of the Out of the Abyss campaign book.
