This strikes me as something like a petroglyph, though with other creative elements, so I'm calling it hybrid faux rock art. I'm totally open to describing it in any other ways you can convince me to.
It could have specific influence in its origin, or not; maybe only my unconscious knows.
The black / line art was created via ZenBrush, and refined in Tayasui Sketches. The colurful painterly stuff was done in ArtRage. Compositing, recoloring, and color varigation via painterly circles for alpha on effect layers was done in Photoshop. The painterly circles of the alphas (for effect layers) were done via the image bomber and other techniques given in my previous post.
There's not necessarily anything representational going on, though on the left you may note some sort of figures or beings. Who do you think they are? What do you see, representational or not?
