Doesnt really seem like there is a strong focus in the picture which really grabs my attention. Maybe try it cropping out the left half so that the sun-lit bush is more prominent?
What is supposed to draw my eye here? what is the main subject? the water? am i supposed to notice that it is dirty? polluted? or is it the little bush in front? if so, why include all the other beanches and leaves also? cant quite figure out the point here
i am quite sure you had the best of intentions, but this is really not what i would consider a strong free-study entry. even though the image could use a little work, the bigger issue is using the challenges to put for images that will engage the viewer and keep them looking. the longer you can hold someone's attention, the more likely you will get a good score. here, there is nothing that says look at me, look at me.
