Well, you can't please everybody...I looked through the past designs and most of the one's you've done are very nice. Well to me, anything that has a Kate picture in it, automatically receives a 5/10, then the rest of the marks are up to you
I think you're dong a good job with the layout. If you are thinking of doing upgrades soons, I would enjoy more emoticons and, like someone else already said, different buttons. (if it's not too much work)
EDIT: hah! I just discovered the "View More Emoticons" button. Scratch that portion of my post.
