Watch your front teeth, had a couple good scares. hahaha
Seriously, most of it comes down to having a good, established form... Sort of like a Kata, or using a variety of them.
http://en.wikipedia.org/wiki/Kata
Like in martial arts training, they rotate through various katas, sort of like moving from pose to pose and learning the fluidity and power between, so that it's all stored deeply and can be accessed more automatically.
I also recommend to anyone, set up a video camera to film like 10-15 minutes of yourself from the front and side, do a little private review without being judgmental, just observational.
If you look awkward, it probably is...
Hand position, shoulder tension, stance...
If you look cool and feel good, it probably is.
