The landscape is surreal. The landforms in the background shrouded by a slight mist that diffuses the sun into a gentle backlight. The edge of the cast net somewhat echoes the sinuous waves of the hillocks.
The skill of the fisherman. If you've ever thrown a cast net, then you know the level of skill required to open a large net like this....especially when standing on a narrow, tipsy platform.
The sheer exotic nature of the setting.
The skill of the photographer in capturing the scene.
