Heres a photo

It's looking pertty nice so far. What is the grass material? Is it RR grass "paper", I haven't seen that stuff since I was a kid, brings back memories
It looks like it is coming up in a couple of places next to the tree trunks.
I know its very early in the process, are you planning on 'dressing' up the edge of the board? You can easily put a small piece of 1/4 round molding on it or smooth it up a bit and paint in a nice complementary color.
In the second photo I see what might be a Pnz IV? Is that going to go in the small "turn out" off the road? If so don't forget to put track marks across the grass when the tank turned off the road. If the "turn out" is a second road I would widen the "turn out" at the intersection.
For a second diorama I think it's coming along well. I like the balance of the trees on the the overall base and the scale and composition of them is really pleasing. Again the grass material works quite well.
Great start - keep it up.
