Nice 4th build. A few suggestions. I believe the paint is a bit too yellow. It looks like yellow green, when it should be a bit more of a tan color. The weathering is a little heavy handed. The handles of the bolt cutters would be made of bakelite.

And, the tracks start out as enamel black. The ones being used a well depicted, but it is unlikely the spare tracks would have a metallic sheen.
All of that being said, if you enjoyed it; you did it right. As I said, nicely done. Again, these are only tips for accuracy and are not set in stone as the only way to build.
