Yeah... tried to make dithering more subtle but the result was just even more awkward. :D

 Thanks for the comments. I raised the mountains in the end and didn't notice the light problem. :)

Feels very nostalgic :)

Nice title, btw.

I don't mind the dithering that much (or maybe it's just because my eyesight is bad...). The only thing which looks slightly strange is the reflection of the sun in the darkest part of the water, as it looks as if the sun is reaching into the mountains. Though that's also a romantic idea...

Still, great work! I love thinking that this could be behind the door.

IMO the dithering should be slighter in the sky, since the rest of the image looks so smooth while the sky is strikingly dithered, it's just a weird contrast of pixeling.
