It's all way too blurry, and you really need to define things better. I see a sky, water, and a beach, but the dark line between the water and sky is just out of place, the random dark blue in the water is distracting because, honestly, what is it supposed to represent.
The sky is very annoying as well, because the colors and lights/darks suggest that the sky is both blue (bottom right of the sky) and purple (top center/left) at the same time. Define your clouds, your sky, and your sun better.
As for the beach, work on giving the sand a different texture than the water and sky. Think it through a bit more. Other than that, not too bad. I like to see people copying me.
