There is a whole lot going on in that tooling. So many different textures and techniques needed to get to the end result. Excellent 3D rendering, down to the bowed boards. I've always been a bit baffled about how to get a good rendering of an object like a 2x4, and you have those types of shapes all over the place.
Clouds, rocks/dirt, plants, framing with coverings, trees, on and on. Nicely done, I can only imagine the amount of learning that had to go into the end result!
