Here is my short opinion:
The forest one makes me feel like a survival adventure story, where the protagonist is trying to stay alive in the wood.
The plane one has the darkest tone out of three, like a thriller story. The contrast of black color and the plane really gives a tense feeling.
The cloud one is the most hopeful and dreamy, I guess it is because of the cloud and sky?
In conclusion, I like the one with the plane because it seems to go well with the ominous description of the story ![:slight_smile: :slight_smile:](https://forums.tapas.io/images/emoji/emoji_one/slight_smile.png?v=3)
