b/c ur not planning on using this for professional reasons, i don't see (legally) why not. just might wanna let them know u plan on making a music vid w/ it and posting it on youtube, cause some ppl might dance for u, but not want it up on there.
and my sis is a ballerina, so if u ask her to dance it'll prolly b the only time u c sakura (naruto shipp) do pirouettes, lol
