there are many different ways to improve your singing technique. I would start with the correct way to breath and breathe support. when you take a deep breath try to expand your stomach instead of your upper chest. your chest should not move while your stomach expands. when you sing contract your abs and control the breathe as you release it. You can practice this by laying on the ground with a heavy book such as a dictionary on your stomach. try to make the book rise as you take a breathe in. Let me know if this is of any help!:)
