i like the colours but i have to say your extreme highlights on the purple armour plates is letting your models down, the highlight is too strong, the lines are too thick and uneven.
I know that might sound harsh but the highlights are pulling my eye away from what would be a very nice looking paint job, i think the flash from your camera is exaggerating them in some way too but they are spoiling your hard work.
also you have highlighted every edge of every armour plate, this is a common mistake, you should only highlight were light would naturally fall and some "chosen" edges that will show the model in the best light.
