I think the aesthetics will be will good especially if you put the level of dedication you put on the plan into the game. My biggest issue is that the scope is going to kill your game either the artists are going to be working overtime or the gameplay is going to hold you back. I think the idea of going down a forest path and interacting with nature is interesting but after some time it'll feel one dimensional. I would try to make sure the gameplay actually is fun especially since this seems more movie than game at certain points.
