Thanks for the tips, Thalnar. Maybe the camera angle is fooling you, though, the gems aren't *supposed* to look like the light is coming from below. As for shading the deck plating, it's hard to say when. I don't want it washed out like most of the other minis end up looking.
It's true, the color scheme is really cool and "khainy" and the yellow-orange blending is nice!
But there are several other things which I don't like:
-The gems have their white reflexes on the wrong side (light is not likely to come from underneath the model) and are lacking depth.
-The hull plates need some good more highlighting on their edges, so do the canopies, and the pulsar needs shading.
-Eldar vehicles look distracting, when the gems come in more than one or two colors. Perhaps if you'd choose one color for them all, the overall look would be more "together".
Still, nice color scheme!
