I don't mind the graphical style

That being said, I did install a texture mod that spiffs up the textures to 1080p scaling, available on nexusmods after a good while playing it vanilla. I didn't even really need to do that, the art and graphical style is pretty darn impressive, which is very noticeable when you're in the black forest at dusk when its rainy and windy....and the lightning strikes lighting up the wet rocks and wet bark. It's really well done.

In case you want it to be a touch above its current level, the mod is nexusmods/valheim/mods/1030 "Willybach's HD"
