i must admit i enjoyed the ParaKiss anime series- never read the manga. actually i first viewed your vector from the perspective of a wall.
so if it was a wall i would say: remove your sig and place to the bottom, move the "paradise kiss" text above the butterfly but below her eyes, i would have used the marquee tool (M) for her eyes- this would allow for perfectly round selections which work-paths can be created. lastly i would have used a bg of say a light shade of blue or perhaps a classy shade of purple. the white bg doesn't properly accentuate your vectoring.
your doing fine work teyemanon.
btw- im glad you got the scans. ;)
