So I was working on a few Lego Star Wars customs this morning... and here's one of them. Lego Hoth Chewbacca. Lego has only released "normal" Chewie, but I decided to make one with a bit of snow like how he appeared in the outdoor scenes on the ice planet Hoth.
I simply added white paint to highlight a few areas where snow would collect on the fur. I also added the white eye dots since the eyes were previously unpainted.
I based the snow highlighting on this scene where Chewbacca has snow on his face.
