Do more thumbnails. The answer to "how many thumbnails should I do?" is always "do more thumbnails." The first concept is interesting, but you need to explore your value mapping more. Where do you want us to look? I assume the center of interest should be the ship and the face, but in the first one it’s the area behind her (?) head, and in the second it’s the palm of her hand, because those are the areas of highest vale contrast, and the size/shape contrast isn’t enough to overcome that.

Hi @Joao Marcedo, I like the two pictures with the space-ship. Seems to be an interesting story. In the first one the spaceship seems to try to escape, because it is more on the right side. The second picture is more balanced. The third picture seems to be under water? It is very rough and I cannot really imagine what is going on.
