Les 100 Marches [WIP]

A burning scene :

The digital painting Les 100 Marches is an exercise of Concept Art in witch I wanted to explore an unusual scene, maybe tinted with fantasy…
I wanted a penumbra vaulted of wet old stones and suddenly burned by rays of light that would offer a blacklight scene.
I also had an idea of a particular camera filter mood. So according my decision of cold shadows and warm lights, I dressed my penumbra and my sunlight with a gradient from blues to yellows.
