Nice finish on this one tankergeoff, the damage detailing really adds character to it.
Only suggestion I would have is to revisit the tracks. The M8 like all the Stuart variant vehicles had rubber block tracks. From your pics it looks like you applied some rust wash to these (may just be the flash) and a dirtier/dustier or muddier look would be more appropriate for them.
Great work on what I've heard is a difficult kit! The interior detailing as well as the overall weathering really bring it to life.
