You've nailed it! Great weathering!! Did you use Vallejo weathering pigments?? How much glue? Sorry for the questions, but they look just great!
The paint-chips don't seem to be that realistic, I would invert those colors. That is, outline the "cut" in white and then put a dark patch in the middle.
Overall a nice paint job and a good go at weathering. The mud looks pretty good but seems a bit too uniform in colour? Not sure. The chips work quite well but IMO would benefit from a bit of rusting to show that they have been there a while.
