That's not a name change
that is another account creation, your original account should be banned anyways.
I know this video wanted to flow good and sync to the music, and you did, but like everyone else is saying:
TOOOO SLOW, ALMOST NO ACTION
Also, a few more things, we need to constantly be convinced to keep watching, otherwise, there cannot be in any point to keep watching, in your video, it is music with no height and lows and at around a specific point of pitch, like a flat world.
There is one type of music that isn't like a flat world, dubstep, but im sure you know what it is, a beginning that drags you in, the drop, and the epic part where you keep your head into the music.
The video itself is good with effects and stuff, you need better music to sync to next time.
