I didnt like your multiple shift, it looked awkward. The clipshift looked good, but the one where you "dropped it" or picked it up and it vanished also looked awkward.
I think you could use some work on your patter. You said "trapping four cards" when they trapped three. Its a small thing but it shows you aren't comfortable with your patter yet, as well as other things in your speech.
I was expecting a poorly executed trick, but holy cow, your clip shift was so quickly! The Multiple shift was well executed, but I agreed with James on working on other variations of the clip shift.
