Not bad. The first one is a little bit too bright for my taste though. I would say that your best ones are the 3rd and the 7th ones. Sometimes simple is better than going all out *pokes Riku avvy*. Still, they're not bad at all. A little more practice and soon you could be making awesome avvys =)
Yes! Yes you have been practicing! Great work. May I ask what program you used? It looks like Gimp, but I've been wrong before. The only one I don't like is the Marluxia one with the lines on his head.
Thanks. I do agree that the avatars look plain and alittle bright and simple. And to your answer Sho, I use PhotoFiltre. Other programs I'm not allowed to use. The Marluxia one...was..something I was trying out.
