So pretty - this is gorgeous!!! The style is such an amalgamation of different elements of nature: I can see your zest for wildlife!
Going from this, I am actually inclined to say 'Green Academia' as your primary aesthetic.
One reason why I think that this would be such a lovely match for you is that, often, Fairycore, Goblincore and even Cottagecore can fall easily under this wider category (the fashion + visuals can overlap); the only difference is that Green Academia is foremost driven by a great passion for nature and the study around it, which i think is a reasonable thing to assume given the care and detail put into this collage.
