That's a very nice looking Terminator. The red is excellent, and the gold has a lot of depth to it. The only thing I see that looks unfinished to me is the red drop in the belt buckle. It may just be the angle, but it looks much less layered than the blue gems.

The blue gems look great, and I like the way they work with the entire model more than the purple ones. I'm going to try to do mine as dark red gems, and see how that looks, but if I don't like that, I'll be going with either blue or green.
