This is a really nice model, and overall has a great cohesive style to it. I wish there was a bit more to explore, with interesting areas that you could invent stories around, but it does have a great start towards a nature exploration game. I think if you had added a couple colliders with trees and houses to prevent walking into them it would help the world feel a bit more real. Additionally, scaling down the fox size to be more traditionally sized and adding the ability for the player to stop and start might help to give the map a much larger feel without having to do too much more work, and give it more of a sense of personal exploration.
