This is a concept drawing of a project I'm working on called "Slumber of the Righteous". There's a story behind this project, but it's too long to get into here. Three angels of God guard the mind of a righteous man during his sleep from attacks of the enemy. The final will be in color, and the angels' wings will form a circular cocoon of protection around the righteous man. But this is it so far. More to come.
