The tones and general shape all look appropriate to me but lighting and fit are a huge part of this. It can be hard to judge any part in isolation, it will be easier to judge in a full or partial kit up.
It is worth noting that on the screen used on the 2 main front panels are clearly leather along with the waist wrap section. The leather grain can clearly be seen here:
The front middle, sides and back are the sections we're not sure on and the focus of the discussion.
For now the CRL, bar the waist, not much mentions materials used. It wouldn't be unreasonable I don't think that level 3, and maybe 2, required leather (or leather like) materials for the 2 front panels.
