If you are stuck on your aesthetic try looking into these different aesthetic branches: The academia aesthetics, nature aesthetics (cottagegore, goblincore etc.), more femenine aesthetics (baddie, boujee, girly etc.), dark aesthetics (grunge, punk, crypitdcore etc.), more soft aesthetics (kawaii, angelic soft etc.), vintage aesthetics and so on. Consider thinking what type of colours you prefer, what decade and what you prefer doing in your pasttime. Aesthetics aren't all about what you wear, but about what you enjoy doing. Try also taking some online tests which will help you.
So, from what you have said I think your aesthetic is either goblincore, cottagegore or grunge plant mom. Here are some grunge plant mom pics: (sorry if they fail to upload)
Here are some cottagegore pics:
And here are some goblincore pics:
They all have a dark twist and have to do with plants, but they each focus on their own thing. While grunge plant mom is a basic mix of the grunge aesthetic with the plant mom aesthetic, cottagegore focuses more on rotten plants,spirits and the darkness of the forest and goblincore focuses more on finding things in nature like gems, bones and mushrooms. Choose the one you like best, or you can mix them. I hope I helped, bye :)
