I think it was most noticeable at the end you did the same exact awkward phrasing and timing as the bucks
In between these two face up cards....your....card.
I think you executed it well, but in my opinion it looks much more magical if you push the cards in the packets at the same time - that way it gives the impression that it's being pushed in one side and coming out the other side, instead of being pushed in and THEN coming out after it's been pushed in. It's probably smoother that way too.
As an aside...what the hell are those cards, lol. They're so ugly ^.^
