I like your photographs a lot. But for this one, I feel that the scenery is just too beautiful to notice the girl. In fact I am quite bothered with the girl in the picture, it seems to ' get in the way '. Other than that I really like it.
This composition is astonishing. One suggestion though... Enhancing the tones of the sky and those clouds which are reflecting the sun, might actually complement the subject's gesture of holding the parasol. As it is, it looks like she might be sheltering herself from rain (there are no raindrops on the water), but the vibrance of the orange parasol indicates that there was good sunlight reflecting on it. That is why it is a pity that the sky is more of a passive element in this shot. Once again, this is just a suggestion... Good work!
