Flippant? Moi? Well, OK, just a bit. But for me, some areas should be in deeper shadow, the moving water could maybe do with a tweak of the definition, and the rainbow is just a fine bit of colour in a very featureless, white centre. I'm not sure where my eye should be drawn - the sunlit area to the top right, the moving water & the rainbow seem the main features, but they are somehow lost. Difficult light, and maybe just impossible to capture it as it was at the time, but it just doesn't do it for me. But hey, that's aesthetics; nobody says everyone has to like everything all the time.
