You’ve effectively taken a fairly large geographic space and you’ve simplified the composition using different visual strategies. For starters, you’ve identified a color palette with limited hues. The composition is made up primarily of gradients of greys and greens. This allows you to keep the composition organized and visually cohesive.
The lighting is very soft and the direction of the lighting allowed you to pull out textures which are especially noticeable in the rocks. The subtle shadows in the stone help not only provide texture but also help reinforce the illusion of three dimensions.
You’ve used informal balance and your image abides by the rule of thirds which helps keep the composition realistic and dramatic.
I particularly like how you’ve included a “stopper” into your composition. Often landscape shots forget to include a stopper and the audience’s eyes risk running quickly in and then quickly out of the frame. A stopper prevents this from happening. The small waterfall in your photograph jumps out of the composition as the “primary object”. It’s supported by a breathtaking and supportive backdrop but even though the backdrop provides the context for the shot and takes up the majority of the ‘weight” of the composition, it’s not the primary focus. My eye races towards the object that stands out, which in this case is the small waterfall.
