No need to make it longer, it's short, straight to the point, nice camerawork, and surprisingly rap music that does not want me to throw my PC out of the window. The movie doesn't outstay it's welcome with the >9000 entries, and is close to being "just right" In my opinion.
The casual drift video would be three minutes long showing the same thing over and over and over again. Yours in contrast is showing something not everyone is able to do without lock modifications etc. and it's much shorter to. Like squidhead said, straight to the point. I would leave it as it is.
Btw: For us younger people (I'm 20) that kind of hip hop music is old school. I guess the track is from somewhen around 2000 or 2003.
