I made the animation for a customer presentation.
Engine sound is from the original and even recorded and music are also created.

Really nice vid and render. The Engine looks amazing! 
However, I think the greenish dark areas are kind of destroying the image. The greenish colors are probably caused by the Hdr and you could simply turn down the amount of green in the hdr in the compositer with a “color balance node”. 
Besides that - great job!
