Great artwork! I especially love the animation you put into the trees. I know this stuff is a steep learning curve and there's a lot to learn. Keep at it. There's a lot of potential here.
P. S. If you're looking for feedback, I see you're using Godot. Check out something called y-sorting for sprites. It's the technique that allows a sprite (like a player sprite) to either be in front of, or behind trees depending on their Y position. It helps add some perceived depth to the world.
