Mr. hats' house. Critz needed

Hi!
You'll need to convey texture on parts such as the hut, trees and grass; the water needs more work (especially in terms of colour) but you mainly need to pin down the light-source: what/where is it in this case? You also need to consider volume (for instance the windows for the hut don't take the hut's shape in count) and perspective (why is the doormat that shape? Is it correct?). You'll need more contrast too.
I like this scene, and I'd love to see improvement.
I'll edit parts if you request it.
