The light gradually changes from the left of the frame to the right. I wonder if this is bothering you? It doesn't look like a definitive sun burst - no rays or hot spot gradually fading. It almost looks like you started to go for a slightly matte, desaturated, dreamy look on the left, but then by the time you got to the right of the frame, you changed your mind and wanted vibrant colors, clear light, no "fog." So you end up with half the photo looking like it got one kind of processing, and the other half with different processing.
There's also a bit of a yellow-green tint to the left side sky and the right side sky is a brighter, clear blue.
Mind you, it's still a lovely picture and it took me several minutes of studying it to figure out what I was noticing. And someone else might notice something different.
