I'm really impressed by the amount of work you've put into this already. I don't always see a solo project that has this much lore written out. the tree models in particular remind me of Baldur's Gate a little bit.
Still, this leaves me wondering what kind of game you're going for. I can guess based on what is shown that you're either going for a mix of Baldur's gate style exploration with a final fantasy/fire emblem combat system or a more open world style game with no fixed story.
Overall, I hope to see what you have planned. I give what you got 9/10.
