There's almost no depth to this. Everything sits on a single layer with each piece saying "Look at me! Look at me!" The water reflection should be bright, but not the same brightness as the sunset itself. Tone down the contrast on the points you don't want the viewer to focus on.
The Clouds have a screwy perspective. You've got these long clouds, near the top, vanishing towards the center, but then you have a bunch with a never ending vanishing point along the x-axis.
The sandy dirt doesn't resemble anything it's supposed to. It looks like a giant scribble and little else. No light source, no anything.
