BMW e46 325i Test Drive, HD, POV

I upload this testvideo of my new Camera setup for car videos. Please comment what you think about this new pov. I use the GoPro headband and the Go Pro hero4 silver for recording About the Sound: i used a closed housing in this video. i noticed that the sound is low. so i bought a new open housing, may be i also buy an external microphone if the open housing is not good enough.
