Learning Independently

Hi there,

I'm looking for advise on my singing. I would love it if someone with knowledge about singing experience could tell me my ups and downs.
I'm nervous that my voice isn't "unique". I listen to my playback after recording and it just doesn't have a kick in it. Is it possible that haven't been practicing correctly?

To practice I start by drinking water. Then I play up and down scales on the piano until I feel ready and can hit higher notes.

Here's my clip on Sutros. http://sutros.com/songs/20445
Thanks for listening. Please reply with advise.
