Your "style" is not at fault. I am assuming that your "form" is, especially if others tell you that your arms go everywhere.
Form, according to me, is how you position your body at any point. Grace, which is something else that you may need to work on, is how you transition from Point A to Point B. Grace is much more difficult to fix, but you can dramatically improve your form by:
A) Working out a bit. If you have more muscle, you will be able to better control your motions.
B) stretch out on a daily basis. If you are stiff, your form and grace will suffer!
C) Emulate other people's form. I have improved dramatically and I continue to improve simply by watching others and do moves the way they do them.
D) Most importantly, PRACTICE in front of a mirror. Let me say that one more time. PRACTICE in front of a mirror. One more time. PRACTICE in front of a mirror. Learn from your mistakes and strive to improve yourself.
