This is one of those cases.
By breaking the rule and forcing the horizon line down below the 25% mark, you emphasize the drama that is happening in the sky. Furthermore, this saves you from trying to get detail in the shadows where there is so little light it is unlikely you will be able to find enough light. The second image is better, though I would not be so quick to change the aspect to a vertical composition.

This is interesting because I'm always afraid of breaking rules since I'm still a beginner
Thanks.
