Thats looking propper.
On the subject of colour I'd go with a lighter shade of green more in the darker Olive drab I use one of the GW colours(with my recent track record with name's I'll modify my answer with its name, once I've gone to my workshop tomorrow
) it gives a similar luster to the original. But is several shades lighter than the Bronze green of the original. But the lighter tone will show off your detailing to a greater extent.Whilst looking very similar to the original colours at scale.
The most valuable piece of artistic advice I've ever been given for display work (and it really does work) in life things appear darker the further away they are . If you reverse the principle and apply to scale .Then you'll achive a greater level of realism.
(Same colour on both vehicles only difference being natural light on the command and energy efficient warm glow on the other.)
