Ending to Lionel Richie's "Truly"

[keysersozeh]

Don't mind the piano playing and singing.. they both suck..  
But i do need help at one thing. How to sound more powerful. 

What I've tried in the above track is to gradually increase the little power i have at the end of each sentence. But i still sound so weak.

Is that all there is to my voice or do you guys hear some points i can improve on that can enhance that sense of power?

[Eugene Steficek]

You don't sound weak in my honest opinion. It sounds placed well and not pushed which counts for a lot especially on the "ee" vowel

[Pekka]

That was not weak, i like it.
