The blues feel too pushed for me in the sky. You've got bright cyan spots in the trees that don't look right-- artifacting of HDR or selective editing. The grass looks nice. A little flat and there's a spot of light around the house that doesn't look quite right. I'd consider trying to pull a bit more detail out of the grass with some local contrast (at least the area with wildflowers in front of the abandoned structure).
I really enjoy the subect and composition. I would consider a BW conversion or a re-work from square one. The processing misses for me.
