Scene mesh is well optimized and is low-poly(not unwrapped), and full scene size is just about 142 547 poly. The scene still looks good close-up and renders quickly. The model was rendered on the cycles engine.There is no post-processing, when you click on render you get exactly what you see on the preview.

WARNING: all models have been exported to FBX and OBJ formats from blender, may not have materials when opened in other software!!!

Enjoy
