Hi,
I set up highlights using Citadel Elysian green and Nugling green.
Then I used oil colors to make some marks and as a filter I used Citadel Asthonian Camoshade.
Next I added some rainmarks and shaded all the details with Citadel Agrax Earthshade. I've done chipping with Citadel Rhinox Hide. Model looks now like this:
I've done similar things with the wheels. For rubber bands I used Tamiya XF-69 then Citadel Eshin Grey and Dawnstone. All shaded with Citadel Nuln Oil.
Now I am going to add some dust and dry mud.
