I must concur. More global life would be help make the world feel more alive.
Maybe the occasional rabbit loping around or a fox or deer peaking out of the woods.
Crabs on the beach or schools of fish swimming around, a whale surfacing or maybe some seabirds flying around above the ocean.
Some lizards in the desert or some antelope/mountain goats in the mountain would be nice.
I really like the birds flying around and I especially love the leaves slowing falling down on one of the combat maps. Really pretty and well done. ^^
