Very cool atmosphere!
The color contrast is striking, and lends itself well to some nice metaphors / narrative if you decide to go down that route. The intro + home with the closed window made me think of a scared shut-in, with an inviting / ever-"expanding" outdoors (maybe it could seep it's way into the home itself as the player continues to harvest seeds)
Overall you have a great foundation, and it's a great visual showcase. Would love to see it developed further, best of luck!
