I love your covers! You have a really pretty voice and a good technique, that's both worth a lot!
And the growls... impressing! My own sound somehow strange and are waaaay too faint to be heard properly while I sing. Oh, and I get aches in my throat in a small time. I guess I have the false technique, I have to work on that.
Are you in a band, Vanessa? I guess you would sound pretty awesome with some nice original compositions behind you.
