Very cool. I especially like the ammo boxes. There's an argument that these vehicles represent everything that was wrong with German vehicle design (and the German armaments industry), being undersized, unnecessarily complex to build, difficult to maintain and excessively expensive. They were luxuries that the Wehrmacht didn't really need and Germany's overtaxed production capability couldn't afford. But they sure make nice models!
I can't tell if it's included, but there should be a second seat on the left behind the mortar. And the mortar base was carried on the rear of the vehicle, beside the rear door.
