You've put a lot of work into very smooth and clean color graduations on the green armor, but I'm struggling to "read" what they want to show: an external light source which is reflected in some areas of the armor? A softened version of the usually rather harsh and sharp edge highlights on Space Marine armor? Or a really nice, creative way of aging the armor by showing how the outer, darker green layer has been rubbed off in some areas, exposing lower, lighter layers of green on the armor pieces that are often scratched by objects or other armor parts as the guy moves around?
The licht source on the base is much easier to read, and also looks very well executed.
