Hi Joe,
Looking good. The few things that stand out to me are;
the inside roadwheels are too clean
the tracks on the turret, hoses on the back and the tow cables also look too clean.
If this is a winter camouflage, I think you should add some more wear around the hatches and areas where the crew would be moving around on the tank. The weathering looks a bit too uniform.
These are just small things, you have really done a fine job and it looks good as is. Perhaps a few tweaks.
Joe
