Zaino'd my car, but...

It seems I still haven't mastered the art of waxing my car. I have the usual telltale marks that I've left - I can't describe it, not quite swirl marks. Now, granted I have a Jet Black car, but still... Is this a factor of improper application or removal usually? I'm using my current car as a guinea pig before I get my M.

BTW, while the car looks great, I can't get over the way it feels, it's like running your hand along glass! Amazing!
