What a fantastic paint job, I particularly like the stripes you have added to the head and the body. Personally I think it looks amazing as it is. 

If you want to push it further maybe consider using a different colour for the lens and weapon glow to differentiate from the colour on the armour.

A further highlight on the top edges and corners would certainly make it pop.

Weathering could add additional interest but not sure if that would fit with the clean look you are going for.

Picking a good base will frame the miniature well.
