Nice, but where are the CIM's pinion gears?
I would comment on the design itself, but I can't really think of much to add. It is a proven design. To tell the truth, what I really want to post about is the picture itself. I find that when teams go for a photorealistic render, it tends to look like a pale/too shiny imitation of nature. Similarly, the plain old screenshots tend to look bad to me because they just look unfinished. However, this picture I like; it doesn't look like a failed job at photorealism, but, at the same time, it also it doesn't look like some random screenshot. Nice work!
