the first one works because of the "statement" quality, the power we all associate with sunsets. your narration is intact. at the same time i'm really
drawn to the sunlight reflections in the water. partly due to their beauty, partly due to contrast, partly because there's not enough of it! the structures surrounding the water are obvious, but a different composition would likely enhance the phenomenon, the totality of the view. even if there's only a little water visible, its placement could enhance the whole in a more helpful way. (at the same time it gives the image a certain plein air-quality.)
or maybe some kind of streak/spot/diffusion of the orange on the left side.. i know nothing and this is not a solution 'cause there's no problem.
the second - i love the sky color! a perfect tangent to your values, on the top of them and completely integrated. it changes the mood, there's a dissonans that is a natural part of the narrative. the relationshio of the wood structure to sand and water is so very beautiful, the reflected sun light building it further.
