Test FJ Marder - Feedback?

Well vehicles don't take as longs as infantry stands thats for sure. This is a test  to see how it turns out. Not sure on the tracks. I tried to make them look worn and muddy but not sure if it looks okay. Probably need a highlight on the edge of the armour plus I have a couple of crew to do.
Like to get some feedback from those watching...
