That's pretty solid, man. Altough its hard to notice due to the dark video, it does look like your throat is open and tongue flat. You've got pretty good pitch there, even though there's no backing track. The one critique I'd offer is to make sure your support is perfect: Stand straight, shoulders relaxed and slightly back. Don't hunch or lean forward because it hampers the great support needed to sing bright and in full chest voice. Otherwise, great performance!
