Your environment is stunning for a 2D game, especially the forest, snow and water scenes.
Have to say it reminds me of The Postman movie with Kevin Cosner
My only concern is the characters don't match the environment, which is realistic with a medieval/frontier tone but the characters themselves are bright and colorful, cartoony. The difference stands out more in motion in the video. But its a design decision and if you like it, then thats what matters, because artistic taste differ wildly.
I wish you the best of luck on your kickstarter and greenlight.
