IMHO,there're too many things in the picture
since your title is sunrise,im sure you wan to draw ppl's attention to the sun
but there's the tree,the foilage at the top,the lady
i just find that there're too many things in there
maybe you could have crouched down a little more to eliminate more of the dark patch of grass below. i feel it has a little too much there and therefore reveal more of the beautiful sky.
