Avoid trying to copy other artists’ styles. Focus on what techniques they have used, then practice using your own style. Push this even further by forcing yourself to make different versions, don’t just stick to one style but try out a variety to see what works best for you.

Experimenting is the best way to develop your own style. As already said, try different versions of whatever you want to draw. Push yourself beyond what you think you can do to discover just what you really can do. Look at what you’ve done without over-thinking it and mark out which pieces resonate most with you. Those are the ones directing you toward what you need to keep developing as your personal style.
