I agree with Casie. It’s about presentation. Song selection and technical skills are definitely a big part but your personal presentation is what will draw more attention. I’d much rather see a dj enjoying himself than a dj solely focused on their mixing. If you’re having fun and dancing around on stage, the crowd will feed off your energy.
Make your own personal trademark. Take Deadmau5 for example, one look at that mouse head and you know exactly who he is. Just use your creative side and make something that’s unique. Anything to seperate you from the rest of the group is definitely going to help you get noticed.
