ok I think it looked nice but the effect could be better. You copy the compositions and mask the characters to grab an alpha channel. Once you have the alpha channel, you could follow elvis deanes effect of turning the characters into particles without any fade. Anyway, nice job and keep workin on it.
Pretty good - reminds me of Sabrina the Teenaged which (a show that has a lot of particle effects in it)
Talking on a non-technical and more artistic level... since her hand motion drives the intitial effect, it should also end it. Right now, the particles initially come out of her finger, but when she reappears, they don't come back into her finger - so the particles seem to go nowhere. However if she seemed to catch the particles with her finger at the end, I think would look better.
