Very interesting contrast between dark and heavy mountains at bottom and very light and warm cloud formations above. Kind of .. Hell and Heaven on Earth. Very good job on balancing the composition on both of them just precise.
If you look at clouds long time (this is general, not only this photo) you can find some interesting formations there. This particular one reminds me the flying phoenix with clearly visible head and wings. Yes, they do exist on my photos too!!!
Good work...
