Lovely job. It doesn't suck at all. The clouds look great :)
Although the water is a little off. The ripples are a little bit too extreme around the girl's body. There should be a bit more around the skirt though. The legs are the ones that look a bit overdone. Just a bit though.
The wall is a little to plain. You should have add some texture. A brick wall would be really nice, actually. Use the pattern for it, but tone it down a little so it still looks like a white wall.
The ground is a little too thick for me. It looks more like a line dividing two different sides on the the wallpaper. Technically, if you think about it, that's what the ground is supposed to do, but this looks like there's some kind of wall. Make that top gray outline a lot thinner. All that outline should really do is separate the ground from the wall. So when it's near the wall, it should be thicker. After that just let it thin out a bit. The bottom outline of the ground is what's giving the ground the "separating wall" look I was talking about. Why is that so thick? Why is it even there? Is it a part of the water? Like the top one, the bottom outline would be nicer if you thinned it out. You should also change the color to something that makes it look like a part of the water. That or, you can just take it out.
The text is almost unreadable.
I really like your idea, and I think you did a great job putting it together. I really like that soft look to it. Overall, good job ^_^
