Branching Bridge

This is a detailed, exotic piece of terrain that'd be perfect for a science fiction or fantasy settings. A very organic, natural feel even though it was created using fractal math. 
There are details and textures everywhere - rough patterns on the hills, bifurcated branchings on the arches, and crennelated crevices at the crown.
