Very nice! Never been good with sakura in SF though :P. Continue the good work! ( I'd like to see more from sf :D)
I think the problem with the head band is that it doesn't look like it's moving in the wind.. but it looks like it's bouncing along with her over all movement..
I think if you put more of a wave movement into it.. it would probably look better..
but I really like all these SvC style sprits you're putting out :-D
