Totally agree with Brash. They are definitely table top worthy. The next step would be to highlight the red and the black on the power armour, especially since we're dealing with primary colours. The blue and black helmets themselves seem highlighted sufficiently, I would focus on gold and red helmets, along with everyone's red power armour. That is if you want to step it up. As is, I would be happy seeing that paint job across the table from me.
