Yeah, that's a great job, and so much so because you have to take it apart before you can begin. I've seen other AFV models where the modeler has added similar detail, but those are kits.
This is an aspect of these models, from FoV, and the other makers in the past 20 years, like 21st Century Toys, Blue Box, etc. They produce models that are like well-detailed toys, I concede, but you can use them as a starting point to produce a truly stunning model of the subject. I've seen builds using the 1/18 scale planes from 21st Century Toys, for example, that have been reworked to hide the seams, then detailed and weathered. It's always cool to see a build like that, and like yours.
Prost!
