Such places like this do exist. On our planet alone we have some amazing and beautiful things that people may not even imagine. When you think about places all over the Universe... MIND BLOWN!!! Thanks for sharing this great piece.
Fantastic atmosphere! I like the balance of the orange clouds on the left and the bright orange of the cliffs on the right. They sandwich the more muted tones of the sky and water in the middle. It's a very pleasing composition.
But I have it on good authority that Peter could not draw worth a damn. Of course, he had lots of time to learn if he so desired. This work is what all the comments say: beautiful, wonderful, realistic, awesome, picturesque, but perhaps the most important thing (apparently overlooked) is that this appears to be an ideal place to hide a chest brimming with stolen booty While I would not call this a photomanipulation, you do say it contains a lot of photographic elements. I do not see them (which is a good thing, a very good thing). Subtlety is king. I tend to discount pictures which use photos when (other than intentionally) edits or blending or edges or whatever are obvious. I do not like heavy handed manipulating. It's too easy to do a poor job - it takes work to do it right, and you, my friend do it right every time.
