Secret of Mana - Gaia's Navel

Been working on creating Gaia’s Navel from Secret of Mana for about two months now.

Used lots of simple geometry and many arrays to complete the map.
I duplicated the geometry over and over again and only learned that I could just create linked objects so the scene is a little slow. Anyone know of a way of doing this easily?

Started with green planes for the grass and moved to hair for the grass afterwards.

All of these renders are using global illumination and a sun lamp. I’ve moved to HDRI now so I’ll post a few of those later on.
