Himani - try and bring more range into your singing by singing more of Lata Mangeshkar and Alka Yagnik genre songs. That is what will keep you in the race in the long run. Otherwise you are excellent.
Vineet - quit paying too much heed to your gregarious, immature mentor and try and concentrate on singing rather than performance. Try wider range of songs as well rather than the Rafi and Sonu Nigam genre only.
Hemachandra - Your voice quality is awesome. Concentrate less on performance and swinging while singing and more on maintaining the consistency in sur.
Debo - same as Hema. Concentrate more on sur and less on performance as it does shake your sur and taal.
Paresh - the journey to victory is long and you are lucky to have survived so far.
Ujjaini - build confidence in your singing and your overall body language. Don't undermine your talent.
Good luck to all. May the best singer win.
