I decided a month or two ago that I wanted to redesign the FF heroines in my own sort of style... so I sketched out Garnet and Yuna first.
Garnet. The inspiration behind her was basically fantasy-renaissance-faire assassins.
Aaand Yuna. I wanted to use bits and pieces from both her Gunner and Summoner outfits, combined with a tribal fusion bellydance sort of look.
What should I do for Tifa? I'm dying to sketch her next.
When I'm done with all the sketches, I'll line and color them.

I am so jealous of your drawing skills, you do proportions really well!

As others have said, Yuna's hair looks fabulous - it's so much more suited to her personality than the hair in X-2!
Her clothes are very well designed and I can see how all of your sources fed into the final piece. 
yuna hair in this just looks super awesome......... the way your designed the dress is really nice and pretty as well
