Here are a couple screenshots.
It still looks like snow, but I've been working on the ink splats. I've made some poly planes, turned them into ncloth and dropped them on the ground, so they got a similar shape. Then, I assigned the ink splat textures. For it not to get a terrible black shadow, I assigned a white image to the shadow shader, but it still doesn't look right and I don't know why! It seems that the ink splats are not as bright as everything else? I don't know.
Anyway, maybe some more on the borders would make it look less like snow.
Ah! Still tweaking the lights. for a million days. And it never seems to get allright =/
