I didn't "edge-colour" this model, but I think especially on the dark parts, it would look better if you do (so now I usually do edge-colour paper models like this ;o)
I liked Yuna's Gunner dressphere outfit from Final Fantasy X-2, so that's why I made this version instead of her Summoner outfit from the original Final Fantasy X.
You can get the parts and instructions to build your own papercraft FFX-2 Yuna (+lots more! ;o) from my free papercraft webpage: [link]
Have fun building!
