Thanks for posting your pics. May I also offer some suggestions?
1) Besides prewar French armor, one rarely sees chain on armored vehicles. Why? Because they have almost no value. Note that most tanks use tow cables. Chains would become entangled and snag suspensions. I'd leave them off your next model.
2) The fenders on the side of a Tiger II were 5mm thick plates used to deflect anti-tank rifle bullets. You've torn yours up as if they were sheet metal. For that kind of damage, the plates would have been ripped off of their holders -- not mangled as such
3) Your spare track links have mis matched links-- some facing the wrong way.
I think both 1) and 2) are because you're trying to match what you see in other models. Try to use your research based on study of the actual vehicles rather than what you see looks cool on other models. Good luck to you and thanx again for sharing.
