An amazing illustration!
Exactly the same technique as the shoebill-tribesman image. Possibly a little ambitious with the multiple light sources. Also, its not necessarily effective as an illustration – there’s possibly just a little bit too much to detract from a central focus. You’ll notice in the thumbnail there’s no figure and no light source, but in the developed image its struggling to be the focus. So, a poster then. See below for detail and bottom for the source thumbnail sketch.
