Generally speaking, it's not original. While I cannot guarantee that someone has combined those exact moves in that exact way, it is a sequence that combines motions that have been used hundreds of times, and in very similar ways to this.
I'll also give the same advice as before, in that you need to get good. Your moves need to be smooth, you need to be good at what you do. This is simply a matter of practice. Keep at it.
And before you teach a given move, you need to make sure it looks fantastic and that you can do it near-effortlessly. Even the best moves look like crap when not performed smoothly.
One thing that helps to unleash your creativity is just knowing a large variety of moves. The more open your mind is to possibilities, the more easy it is to have unique ideas. I would invest in products such as The Encyclopedia of Playing Card Flourishes, Xtreme Beginnerz Vol. 1, The System, The Trilogy, Generation Extreme, Cradle to Grave, Genesis V1, Project AVIV, etc.
Don't get them all at once, and don't get any that you really don't want to. However, if you get ones you like and, bit by bit, one by one, learn the material on them it will really help to broaden your horizons.
Best,
