There are so many technical elements you’ve managed to incorporate into this scene with great precision.
For starters, you’ve used a limited color palette of greens and blues which has helped you organized your composition of this large scene. You’ve also abided by the rule of thirds and you’ve managed to incorporate a strong sense of depth by using objects in your foreground, middle ground and background. This helps provide the illusion of three dimensions and helps give your audience the perspective of “being there”.
The more artistic elements include the photograph’s texture and the interesting use of weight in the reflection of the forest in the water.
Photographic water is often tricky because depending on its prominence and the lighting of the day it can be either dead space, overexposed, oversimplified or just boring. All of these elements detract from the overall composition of a photograph. However, you’ve managed to capture still water during a beautiful time of day and you’ve used subtle texture and reflection to make this area of the photograph interesting and engaging.
