Speaking of balance; there are many ways to balance a piece. There's color balance, value balance, male/female geometry balance, etc. Have you read the articles from the links on your other post?
I've simply gridded your original piece using the "rule of thirds".
Can you see how there is basically nothing in any of the bottom quadrants?
This makes the bottom unneeded. Instead of just cropping it off there are several options. Now if the bottom was a dark value it would compliment the sky being a strong contrast. Another option is to put more "rocks" so there was a balance of shapes. Depending on how/where you placed them, this could lead the eye up to the "house".
There are really so many options that the best advice I could give is to try to learn the very basics of compositional theory.
I've only touched on the tip of the iceberg concerning the "rule of thirds".
I'd like you to try to post your thinking back. The reason is as you try to explain the elements that do/don't work you'll be solidifing your understanding and building your art "vocabulary".
I'm happy to keep doing these digital alterations (and giving more explanations) as long as you put in as much effort as I do.
