is my singing/dancing good enough for sm, jyp and yg?

hey everyone! i have been working hard to improve my singing for some time now, and have dabbled in dancing (mostly in my house. alone). I was wondering if you guys could watch these and give me suggestions:http://www.youtube.com/watch?v=jtwCcrLhNfc (Chinese Zhang Liyin Song)http://www.youtube.com/watch?v=wd00MiHqAC4 (Korean Park Bom Song)http://www.youtube.com/watch?v=_yvnhIP0K-Q (Dance)
anything is welcome! i definitely still struggle with my singing (blending head voice and chest voice...do i belt? do i "switch" voices? is it noticeable?) and i also have trouble with the korean (i'm chinese). thank you so much!

Well...the pronunciation of the lyrics is important. What are u doing dancing there? Is not pop or freestyle. But you have to practice a little bit for the singing. The dance is really good. The next if you are going to Korea, the judge can you explain better than I. You know the judge for K-Pop Star. Go there and try. I hope, the you have luck for that...
