It's nicely contained, since there's no sky in frame. That concentrates attention on the land.
It has depth - foreground, mid-ground and distance.
Though the mid-ground has the light, it's the distance that draws me in (I want to be on the hill - I imagine being there). So my eye, after a moment of distraction by the dominant light, goes there to find engagement first.
Then, from curiosity (as in "have I missed something?") it sweeps downwards, hardly pausing on the middle reaches that are the best-lit but not terribly interesting (unless you're a student of forestry), to explore the watery foreground, where the delicate creases of the water are discovered. They are recessive - they don't shout - but are sensitively significant.
The house provides a keynote without which the whole image might be seen as too diffuse, and a reference of scale. You might say the same of the boat but it's less important, though there is a minor dialogue between the two within the picture-space.
