This is a really good start ^^
First of all, the 'styles' of everything is different (the water is 3D-ish, the stars looked vector-like, the
girl is anime, etc.). The thing that stands out the most is the water, it looks too real compared to everything else. I
suggest to make it simpler - less detailed, but not so much that it looks like a one-color block of blue.
The stars look like the same brush used over and over again. You should use some variety. You should get a better star
brush, or make some stars on your own from a tutorial. You can find some really good brushes on deviantart - look for
the ones that look like the image on the tutorial aozoraskies gave you (http://gallery.artofgregmartin.com/tuts_arts/making_a_star_field.html).
The moon is fine the way it is.
The clouds could use a bit more work. I see that you used some for the fog. You could either find a good fog brush
(which I've tried to do and failed miserably) or use a tutorial. Depending on what program you use, some or all of
these tutorials may not work for you:

The tutorials are Photoshop tutorials that I googled. If none of these can help you because of the program your using,
you can look some up on google for your program - which I'm sure you know how to do.
The clouds in the the sky will look fine once you've put in those new stars I suggested.
The tear drops are a good idea, but it does need a bit more work. It doesn't look very believable. A thick line
down will only work as tears in a chibi image. I suggest to redo the tears after a look at some computer graphic making
tutorials. There are too many sparkles, take some off. (If you didn't make the tears, you may ignore this paragraph
or try to remake them yourself).
Great extraction. Girl is looking good. This isn't a big deal, and it's not even that noticeable, but I agree
with aozoraskies on the colour. Compared to everything else, the girl looks a bit purple. Try to give her a more blue
tint.
I really like your title. But those lines in between in the words bother me. It's a good I idea, but I have to say
that those line are really thick and almost distracting. I say to make them around one pixel in width. Making it fade of
the sides would be really cool too - you can do this by using the 'Gradient Tool' in Photoshop. Don't
keep the bottom lines, but if you want to keep them, I suggest make the width on pixel and make them barely noticeable.
If you do this, you should rearrange the text so that they aren't too far away from each other and, well, look
good.
EDIT: Don't overdo on the stars though. Don't make them look to bright
or they'll distract people from looking at the whole wallpaper. Actually don't make anything too bright.
