I've work whit Kray and it've seen very difficult to me get "deep color". I think that these images are very " deep color" maybe too much,
I don`t know what do you think about that?
Looks good, but some images have an "open-GL" look to them, as if they were rendered by a realtime render engine, I think if you read Johny's suggestions (he's posted a lot, so it will be easy to search and even print his posts) you will be OK.
The first thing that Im getting used to when working with Kray, is to think in physical terms, where no surface should exceed a diffusion value of 100% that is the golden rule to get good materials, basically the % amount of the reflectivity and diffusion (and transparency, as needed) is not to exceed 100% , I think most agree that actually 80% on the diffusion channel alone should be tops.
maybe try desaturating some image maps a little bit and working with the 2.2 gamma linear workflow (also explained throughout the forum)
