WWI M1917 Model T Ambulance

Hi All, Model car of a different sort. I just finished this RPM 1/48 scale French M1917 Model T WWI ambulance. This is my time applying earth effects beyond just dusting with pastels. Overall, I am okay with how this turned out from a weathering perspective, but there is room for improvement. I learned some things that should make the next model I use these kinds of effects on look even better.

Thanks for looking.
