Cool, it looks like an epic landscape. Here are two landscape paintings, both by Albert Bierstadt (I made grayscale)
Left: The Rocky Mountains, Lander's Peak (1863) - Right: A Storm in the Rocky Mountains, Mt. Rosalie (1866)
They’re both mountain scenes with a bright highlighted focus point in the middle ground.
In the left, the values are mostly arranged in horizontal shapes, and I think that makes it look more peaceful but still wonder where the path goes. On the right there are strong diagonal shapes, with some going out the top of the page, and I think it makes it more exciting or even dangerous.
I think your composition is also pretty horizontal, if you want the quest to look riskier you could make more diagonals.
