Since the last post I've now added the two base layers of static grass to the entire diorama and started to add the heather bushes. The third layer of static grass will be added when the heather is in place to fill the grassy gaps. I'm going to hold off on showing the current states for now, but Bryony thought it looked so good that she wondered if I really should add the purple heather flowers as she was worried I'd ruin it. So that meant I had to expand on my previous small heather experiment to see how a bigger area would look.
Personally I think this looks horrible which is a shame as I thought the small experiment showed promise. So unless I come up with another approach for doing heather flowers in the next ten days then I'm going to leave them off and assume that the diorama represents a time of the year before the heather flowers. I guess you might call that cheating, but I'd prefer to leave the flowers off than completely ruin the model.
