Something in the way of woods

All vanilla blender work.
I have spent all day modelling the grass, setting up the particle system and deciding how to properly show it to You my friends, I understand this may not be the best environment for this work and for that this is on the WIP zone, so I hope You can give me some tips or advice. I have a lot of ideas, and a couple of details to add, like re make the eagle in the shield and some ornaments of the sword.This PSystem is very taxing ,hence time consuming. I am not so new to blender but again, any advice would be of great help!.
