Hey everybody.. I have a big problem and I need ur help! I've been dancing for 5 years and I've learned the basic movements of different styles..like popping, house, hip-hop and so on.. but when I dance for myself or when I improvise.. I can't use it! I dance like a 6-year-old girl.. What am I to do?? How can I lear to use the base?? Btw I'm 16..
