Very very nice mountain now!
I also like the patches of yellow flowers.
If you still have patience to play with that setup:
Yes - back to the bigger trees please
If you have place and PC power left, I'd think it would be nice to have another population with grass.
I'd try the GRass_Blender_FInal_Late_Summer.tgo from Chris quite dense but not too big.
What do you think?
