yes, I agree on the green gems. They look a ton better.
I also really like the high contrast, and the bone chest plate looks ace.
If I may nitpick though, I see you left the heads black, and to me that means that they don't get much focus from my natural movement of the eye compared to the brightly colored chest and weapon. Usually, people want the heads of models to be a focal point, as that's what people look at when they look at a person too. So you could consider painting the helmet or the faceplate (or both) in bone as well.
Other than that nitpick, they look great. The black has been highlighted well, the bone looks superb, and the green gems just pop!
