A few quick tips which you may take or leave.
Spread all the cards face up first. Show the audience all the faces.
Cards are placed face down on the first three packets without displaying. Then you do some display with the fourth. What's going on? Why the difference? This strongly suggests cheating (which, of course, you are.)
You vanish a card from the first two packets but not the third. Why? This seems odd.
As I see things, it'd be better if you vanished a card from all the packets or none. If you vanish from all, vanish in three different ways. If you vanish from none, again use three different moves.
