For your first wallpaper, this is good. The scan of Haruhi and Tamaki is very nice, and you chose good screencaps for the border. The bg work is nice...I'm not one for pink, but that's just me. The effects you used in the bg is nice also. The only thing I don't like, is the text. The font is very distracting, it draws my attention away from the actual wallpaper. So, that would be the only thing that I see, that I don't like. :)
Very good work all around though. X-P
