Looking very nice indeed, lovely piece of modelling and painting skills on display..
If I can offer one suggestion.. the Beute Panzers had the problem of being fired upon by their own side, so most of the artwork (and it is mainly artwork rather than photographs) show very large identification markings. If I was a German riding around in a Soviet Flamethrower tank, I would want the biggest Balkankreuz possible, just in case some sharp eyed 88 gunner decided I might be hostile. So large and hurriedly painted German markings seem likely.
