For all of the pictures I had to get rid of the floating particles :( For most of the pictures there have been minor changes. I readjusted my Dominate Directional light, and made the shadows crisper for the world so you can catch some of the cool shapes they make:
In this shot I added a lot of decals (the figures on the giant red wall to your left), and readjusted the eggs to that more of them would catch the light. I also moved the eggs completely into the fence.
In this shot I added blood decals trailing off the side of the vista. I also adjusted the pots, and changed the fire so that you can now walk off the edge of the vista.
This shot changed a lot in the middle-ground. I took out the old gate, and scaled up my bone pillars. I also pushed the pots out of the foreground, and replaced them with a stegosaurus-plate fire coulombs.
