Thanks for the comments much appreciated.
I purchased the leaves from the internet. I think the company was greenline.
I tried to convey the image of a machine gun squad marching down a country road in Autumn.
I noticed that lightly used roads sometimes have a green strip of grass and weeds in the middle that has not been disturbed by wheels or feet.
It may look a bit funny as I had no room to place ditches at either side of the build.
This is why other eyes seeing your builds and giving constructive comment is useful.
