Excellent rendition of Wind. Also, don't forget, Wind is a cooling agent, major part of Ice Release. I'm only mentioning that because it's a great way to combine elements with wind, as wind can serve to lower their temperature, and achieve a damage bonus through there. For example, while you can't create ice, as per se, you can combine a strong wind with a strong water technique, making the water sharper and faster, and even colder, acquiring a certain tangibility due to the small formation of ice crystals, which will add to the piercing bonus. It also works great in cylindrical techniques, as the sides of the vortex will have crystals, which will make the vortex sharper.
Also wind is a great scattering agent, bringing about expansion and dispersing the element you're using it against or with. This will allow you to, for example, use it with a water technique, making it reach a longer range, or attack a larger number of targets. Also, scattering the water, while make it colder, allows you to bring forth ice crystals faster.
That's it for water. Now, with this new knowledge in hand, along with the description you made for wind, how can you use combinations of Fire (give it a little bit more description than the one you gave), Earth and Lightning.
