Although the double undercuts and fans and other stuff were not perfect, I was actually quite impressed. Although unneccesary, it shows that you have learned something and that you can do many things in one video. It's boring to see some videos showing a 2 second clip of the snap change, so adding other stuff adds to the flare

.
May I ask where you learnt the majority of your sleights? Your double undercut was a bit awkward. Once you've taken the bottom packet, clip the packet between your index finger and your thumb so that there is a big gap to insert the packet to the top. Then use the length of your thumb to square the packet up with the rest of the deck.
Hope this helps!
