I really like your choice of colours. The shade of blue works really well, especially with the dark red. I struggle to get my models to standout from one and other when in units (often looks like a smush of colours), but the way you have contrasted pale armour with the dark greens and bases really makes each model standout even in an orky-crowd.
Annnnnd the strong colour scheme makes your force look really cohesive together too.
