I'm just going to be blunt with you, so don't take this as me being rude or mean, I'm just trying to tell you what I saw from my perspective and hopefully you learn to grow as a magician from the constructive feedback that you receive. First off, turn that crappy music off in the background and actually speak to the camera as if you were performing for a spectator. Not only will this help with your practice, but also with real world performances. It also makes the viewer more interested in the performance. Also, next time you post a video, keep it at chest level! Get a cardboard box if you have to or buy a cheap desk from Ikea. Watching your angles is very important in magic.
Now onto the routine itself. Frankly, your sleights need a lot of work, as well as your ambitious card routine. I suggest that you buy the new version of Born to Perform Card Magic with Oz Pearlman to help improve your sleights, as well as give you a great ACR. When you have mastered that material, get Extremely Ambitious by Jay Sankey for more ACR ideas.
I honestly had no idea what the heck I was watching with your video. You need to stop fiddling with the deck so much and trying to look 'hard' for the camera with the flicking and twirling of the cards. It doesn't look flashy, it just looks sloppy.
Just to give you an idea of what a proper Ambitious Card Routine is supposed to look like, view the videos below and learn from them. Keep practicing and don't give up. Work on your ACR and other sleights and keep posting videos. People will give you feedback and it will give you an idea of what to work on. Good luck!
