Nice. I like the different more clean bone look you have chosen than most Deathwing models are seen with. Needs a little contrast but still looks good, maybe the highlights and midtones could come up a touch to reduce the grey but that might be the limitations of a acrylic white I assume you used. Green is great. Red needs more contrast, too much highlighting would make it cartoonish but maybe some more shading would work. Plasma could be better.
