I'd just like to say as an avatard, your username made me very happy!
Now for the rate...
I'd have to suggest adding another color to the theme, like if you use the pink, use little pink accents all over the avatar, it's the little things that pull an outfit together, and I'm goin to agree with Bunni, lose the little bowtie, too much yellow on yellow.The cat on the shirt, added balance and to cover it up, although it makes the avatar more complex, it also throws off the balance.
