Love to see the cross-over project! And to boot - goin' small scale.
Ok - so it's not historically accurate, it's not scenically accurate. On a 'fun diversion' project like this you're not going for that and that's fine.
I really like to quantitiy of figures in this, they are everywhere. There is a lot of detail too.
My only critique is the size, you could have chopped off about 3" on either side and this diorama would have focused the viewer right down on the road and into the action.
You know what would be cool - a front photo eye level down the road.
