Erm. There should be ...

[Ai no Tsubasa]

I think that this site should have make a Dream Avi option on here, that way it would be easier for most Midoreaian's to know what they want their aviatar to look like.
That and the ability to preview items on your avi when you are shopping in the shops.

There is a Dream Avatar creator, called "Midorean Avatar Dreams" or MAD for short.

I love your link Kupsy

Anyway, yes, there's MAD for all your dream avatar making needs. It needs some updates, since the person taking care of it has been busy lately, but most of the commons are there.

The option to preview clothes in store was discussed before, and I think it was part of the plan when we had a coder (a while ago). But he disappeared before it could be implemented.
It could be a nice addition at some point, but realistically, there are many things above it on the to-do list.
