I use it on my natural island, Muir Wood -- or a variation of it, anyway. It's currently a dirt with maple leaves and I'll probably switch it out during winter for a more snowy look. I think it does really well with more natural island themes? I don't plan on using it for my second island, though, since I'm going for a more cultivated aesthetic and will probably use the in-game stone paths.
I don't mind the lack of sound since I don't usually play AC at a high enough volume to notice unless I'm really listening for it, honestly.
