Here are some styles from the d20 SRD, for those who don't know what styles are.

And without further ado, let me present my homebrew styles for critique.

Kazejutsu, the Way of the Wind
Developed by the elves, kazejutsu's techniques are mostly defensive, but the style has powerful offensive capabilities as well. Monks who practice kazejutsu attempt to emulate the wind, evading an opponent's attacks, always just out of reach, until the proper moment and then delivering a crushing blow, or gradually wearing down an opponent with lesser strikes as the situation demands. Grappling is anathema to kazejutsu, unlike many other martial arts styles. The key to kazejutsu's effectiveness is unhindered mobility.
