Very nice! ^_^ I like the colors and patterns you added. It's a bit bright but not overly so. The text and font you chose is fitting as well. Although you left the word "icons" on the far left hand side. You might want to remove that ^_^'
The only other things I would suggest are to add a signature on the very bottom. "wallpaper by: <your username> @ minitokyo.net" or something similar, that way if anyone rips it you can verify that it is yours. Also, try making it in a bigger resolution. Not many people use 1024 x 768 anymore. ^_^
Overall you did a great job! I love Tsubasa, and I hope you continue to share your work here. :)
