i'm on the border of showing this here, but it's by far my favoite forum to check out. Maybe you guys will like the zbrush work I put into it. =)
so the mech was modeled in Max, the snow and penguin, were made in zbrush the trees were detailed in zbrush and some of the mech was detailed and created in zbrush (about 5%)
used zbrush to render the trees.
