A few flower heads can be added, and I do mean a few. It is very easy to overdo. I load a small stiff bristled brush with pva and then wipe most of it off. I think touch the brush onto the tips of the longer grass fibres where I want the flower heads to be. The coloured scatter, some green can be added as well, is then sprinkled over the glue and left to dry. Once dry the excess can be vacuumed off.
To finish off, the tree is planted into one of the rock fissures.
The photos below show the finished diorama which will be used as a demonstration example.
I have a couple more dioramas to make, so more entries to follow on my blog soon.
