It's hard to follow your video because it has a lot of elements that just don't make sense. The tape on the arm, the balls, the tissue paper, the pikachu, etc. 4 minutes for such a mish mosh of randomness is about 3:30 too long. Sorry man, I can't say I like this.
Try focusing on one thing, cards for example. Spread them, cut them, do some flourishes, etc. Film 15 minutes of material and then edit it down to two minutes tops. I think if you can focus the video on a single topic and deliver material on that subject it'll read a lot better.
The music selection also was something I didn't like. It's a personal thing for me. I don't know if that music is something cultural to where you live, but for me (someone who lives in California, and doesn't speak or understand that language) it's a distraction.
All the best to you, and keep up the good effort!
