I don't like the PS filters. Font's tacky and overdone, as other people have said; go for something much simpler with only one outline and no bevel, and also pick a color that's similar to the colors of the background, because that shade of blue looks out of place right now. The black glow around the two figures also looks out of place; try a lighter one instead. In general, I think the figures could blend in better, particularly with regards to color. Right now the difference in saturation between them and the background is weird-looking, and the figures are also somewhat purpler than the background, I think...and something else is bothering me about them as well, but I can't quite put my finger on it.
That said, I do like the sky background pattern, especially since it only takes up a narrow bit of the screen, but it could blend into the white better, especially at the top. Try making it look like it's fading into a cloud or something instead of whatever brush you used there, maybe. Oh yeah, and for the stuff at the bottom, use fonts and colors you used elsewhere, like for the title. It looks kind of haphazard the way you have it now.
Also, what's with the Japanese text or whatever? That kind of thing is overdone and looks bad, imo.
