If that's the way you act normally in a game, it's good.
From the point of view of what I consider normal behavior, why would you keep your right hand glued on the table at all times? Gambler's flat palm is designed to allow you to get into a varierty of positions that look very natural. In practice you will find most of them easily.
Also, if you don't shuffle the cards in that manner regularly in a game, the move is useless in a game situation.
Have a nice day,
