Modeled, simulated and rendered using Blender 3.2.
Viking boat was modeled (probably not realistically accurate) with all the ropes and parts, though it's hard to see from these images. Maybe I will post details of the actual boat later. It was fun modeling these trees as well, all of the background trees are cutout billboards of trees to save on render times.
I also want to try to render this with different lighting setups or types of clouds (all of which are procedural volumetric clouds). But maybe later.
