Sure, no one can specifically tell you what "your element" is, but they can lead you in the right direction. Finding your element is as simple as working with each of them intimately and connecting with one of them. Keep in mind your element is not the one you find cool or the most "powerful" it is the one you are most at peace with. The one that comes almost naturally. I suggest starting with the element that corresponds with your Zodiac Sign. Of course, you should not stop there because there is a high chance that that wont be your element. Work with them all.
When you do find you element that doesn't mean you should solely focus on it either, you should continue working with them all. Make them all comfortable for you.
