Fantastic work, indeed. I agree; a tan or brown filter would be perfect.

I'd hoped to be able to provide some piccy evidence of progress on this but I'm temporarily unable to access the photo files due to a change in ISP. I have now; Applied the first tan filter- knocked back some of the contrast, but does need a coat or two more; Gone with the kit tracks- painted up with Lifecolor and cut roughly to shape before being secured to the running gear with CA - not too worried about how it looks as it will be hidden behind the new side skirts; Done some more work on the sensor head- the inner surfaces of the "eyes" were hit wth Vallejo Chrome and then Tamiya clear ( Blue, Green and Red) were added to create lenses.
