When photographing a landscape while standing you produce an image that is the same as you would see without the camera. One seldom kneels to view the scene before him. That would be an unnatural perspective: NON?
It may be somewhat "unnatural," but I also think a lower perspective would have given the photo a greater sense of depth. If that was what you were going for, of course. I like the colors though.
Fill the frame, here your subject is the field with flowers, make it look even bigger by standing closer. It will only produce a stronger image. The only thing I regret from my last trip is not filling the frame enough
