There are many moves where you want the spectator to be looking straight on at the deck.
Tall people work for short and vice versa. When you angle on a move is important, raising your hands up or down doesn't have to be (and often isn't) the best solution. Instead , try tilting the deck so they can only see what you need them to see
Imagine there are threads coming out of their eyes. Where do these threads hit? if you tilt back end of the deck downward, they will not be able to see anything going on behind it.
Being tall, when working for people seated or shorter people, I need to tilt the front of the deck forward towards the floor to cover some moves. I do NOT lift or lower my hands.
Now, I do not own Fallen, so the "tilting" solution may not work depending on what you have to do for that trick to work. But, it's a good toolbox to keep in your bag for times when you might need it.
But regardless, always remember that you should NEVER perform a trick if you don't feel the situation will allow you to do it to the best of your ability. You don't have anything to prove. And while you might be chomping at the bit to show off your new trick, if the trick is worth it, then it should be worth waiting until the right time and place that you can do it justice. In the long run, people will think more highly of you and your work.
