First I want to commemorate you for flat out doing a Kaleido Star wallpaper in the first place. KS is an under-rated anime, and although season 2 was total crap, season one was one of the most enjoyable anime I have seen in a while, so for that I want to thank you. Second I want to say that I like where you're headed with this wallpaper. The main picture just seems cut off by all the wording, but is a great picture to use. I would suggest making use of the sides, by having the words and phrases kinda slide out from underneath the bottom of the character. This is because the character is the focal point of the wallpaper, with the words being second. Cutting off the character at the top like this only takes away from that vocal point, and in the end confuses your viewer. Once you rescale or move or shift your main picture, I'd consider maybe decorating the background if you want, but it is fine (the background that being) the way it is now. Keep up the good work, I like where it's headed.

Adding to what the above members said, try taking a look at Deto-15's wallpapers which makes use of text to a great effect ;) Less circles will be nice too.

That blue is bad... maybe more something like the hair of the character are like... and the running of it should be more smooth... and why does the half of the head have to disappear in the outer-scene?

but I like the idea and the composition!
