Sierra Nevada-Inspired Alpine Landscape

Hi there! I haven’t really posted a lot here on the forums, but I thought I’d share my project I’ve been working on for the last week. I know it’s not as good as some people’s work here, but I’m fairly happy with it. I think the snow really needs improvement, as well as lighting and material blending. I used L3DT to generate 2x 2048x2048 heightmaps, then blended them together with the sculpture tool.
