His come back from there and journey so far has been full of crests & troughs. While he survived the veteran judges like Shiv-Hari & Khayyam, he was voted out by people, here I'll try to assess his strength & weakness:
Strength:
1.good tonal quality of voice,
2.can hit high notes pretty well( in AS's words high range ka singer)
3.has good expression
4.can open his voice
5.sounds pleasant( mentors & judges described this as 'rooh se gana')
6. without any training, gave tough fight to fully trained singers.
Weakness:
1.Because he is untrained goes out of sur
2.can't sing at low notes
3. fit for few songs only at the moment, seriously needs riyaz.
Wish him all the best for future..............
(with due respect to him & his fans)
