Hmmm, I don't peronally like the sunburst. I liked the depth of what was there on the left in the first image. Is it possible to remove that sunburst and take the image into a graphic program and do some painting in of some various degrees of darkness, using a paint brush, smudge, soften, burn etc, to the tallest of the mountains on the right? Maybe do a search on the net for some landscape paintings and examine how the artists have used light and shadow in mountainscapes. The mountain on the right is starting to look better. The base of the mountain and the land in front of it would be considerably darker than the middle or top because the mountain is blocking the sun from that area. The lighting in the top image would be bang on if the sun was not in the background, and was off to the left, and off the image.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
