Looking very good, I like the different tones of grey you are getting so far and the tyres, are they Azimut?
Just a couple of things on the markings, the rear Dietrich should be on the boot, and the tactical symbol for the motorised Division (or Brigade) should be on the front and rear port fenders.
The style of Dietrich doesn't look quite right, I think I have some that would fit better, I'll have a look and send you them if you wish
Here are some photos to help.
Interested in and researching the vehicles and weapons of the Leibstandarte
