Hip Hop dance is all about selling your performance and making people go wow. You should focus on every move that you do and you need to be very confident about every move that you do.

When practicing always remember that Hip Hop dance is all about the isolation of different body parts so make certain you know which body parts needs to be moved first and in what sequence they need to be moved.
Once you have practiced and mastered moves, you will be able to start putting them together to master more difficult Hip Hop moves.
