Olmec Giant Head Statue

I like ancient cultures and wanted to make a 3D model of one of the Olmec giant head statues.
Some technical stuff:
Geometry : 1788 Polys / 3576 Tris / 1790 Verts
Textures size : 2048 px
The workflow:
It is sculpted and retopologized in Zbrush , unwrapped in 3dsmax, then it is baked and textured in Substance Designer using procedural nodes, so I can play with the random seed and some other parameters in Unreal Engine.
