Heh, I picked out the 300's wheels as soon as I saw the image. That angle is so right for the GT-R; I find from certain angles, it looks very dated, and this one accurately shows the brutalness of the design (after finally seeing one in person, it really is the case!). This is what I meant by my Z not being cleaned up enough; the amount of time you spent on this is absolutely incredible, and it shows.
However, I will agree with Moglet that it seems a bit over-sharpened. Looking at it almost gives the impression of manga, with the very defined differences in the reflections. It's no bad thing; as has been mentioned countless times, your work has started to take on a less realistic aspect and a more artistic one. Because of that, I don't mind the blue tone (a monochromatic look is kinda your style too, anyways), but it does mean we miss out on the very nice background colours Marunouchi provides. Also, this is just the angle, but the side mirror really gave my eyes a problem when I first looked... I thought it was a very strange reflection!

My favourite bit is the front wheel flare. Such a nice reflection, just awesome, and I'm flattered that you mentioned the Z. Keep showing us how it's done 👍
