Very nice finish on this one Omar. The weathering looks fantastic - there, but not overdone.
I would like to point out a few minor things I noticed. First, the 2 small holes over the driver's vision port shouldn't be grey. The next thing are the handles of the wire cutters. They were made out of bakelite, not wood, and should have more of a burnt sienna color. Third, there were actually short extensions under the rear fender flaps that block off the holes when the flaps were down (you could always say that these were torn off or removed for some reason). And finally, it's hard to tell in the pics, but it doesn't look like the 4 small lenses in the convoy light were painted.
Like I said, small things....
