Ah, that makes since. I get those aesthetics aren't for everyone, and in glad you can recognize that.
Could you do dark naturalism?
Color pallet (with codes)
Some images for reference (using these images is not needed but not unwelcome, and none of these are mine btw)
I really don't have any specifics other than that, feel free to incorporate whatever other aesthetics or touches you want, I'm mainly asking for another person's view. Despite there being baseblocks, all aesthetics are kinda up to interpretation, and I find it really interesting to see how others view each one. Tell me if you need more info, and don't rush yourself, I know that making this stuff is hard. Thank you <3
