This painting escapes the cliche nature of so many landscapes. With the use of the shroud of fog, you've created areas that both arouse curiosity and keep the eye on a very clear path from the mountaintops in the background, to the darker peak on the left, to the craggy tree and then finally to the twisted boulder in the bottom left and the bright blue wildflowers in the grass.
Each element has a surprising amount of character. The shapes of the peaks echo one another, hinting at similar mineral types, and at the same time have originality in form. Each is believable in its own way, making it even more impressive that you've done this entirely from imagination.
The real star of this picture is the craggy tree. A simple change in perspective might have brought everything out a bit more; making the tree larger in the foreground and the other elements slightly smaller, the tree itself becoming a study of the twisted forms of nature. Some color brought onto the bark, perhaps showing the disease that deformed it, juxtaposed against the beauty of the ancient landscape demonstrates the fallibility of organic form and bring the viewer to wonder - what's different between the stone and the tree, when it comes right down to it? Everything is worn smooth and changed over time. One simply lasts longer than the other.
All in all, a fantastic piece, worth the rare fave I'm giving it.
