It's weird, isn't it? There's nothing overtly scary about it, but the image still feels... off.
If you think about it, that feeling comes from contrast and juxtaposition:
- The boat isolated in the landscape, on the sand and not in the water, tipped not upright.
- The clouds and gloomy blue light vs the inappropriately intense red light in the cabin.
These elements combine to make us feel like something bad is going to happen in that cabin, if it hasn't already.
