You are more likely a Tenor like 80% of the males in this world.Most of us think we are Baritones because we are more comfortable singing below F4 and we sound funny above that. But it is the Quality and strength in our voice below C3 That makes a Baritone or Bass.
This mirrors what I was saying about Confidence. "Being confident and questioning whether you sound good or not makes a difference in the sound being produced. When confident you naturally take on a stronger more focused full sound and when not confident you end up with a week timid shaky small voice which just makes it harder to control."
The weak(yes, I wrote week before. so sue me....) Timid, shaky, small ,voice comes from not wanting people to hear an off pitch so you sing more quiet on those parts and mess yourself up. So, like Kickingtone said, practice somewhere where you can screw up without feeling self-conscious and let loose the singing god within.
I hear voices in the background. It may only be my (vivid) imagination, but you sound to me as if you don't want to attract too much attention to yourself. You sound as if you are singing to yourself.
If you are singing somewhere where you are not yet comfortable, I advise that it is an absolute MUST to find somewhere where you can relax. If you don't, you could end up training all kinds of inhibition and nervousness or tension into your voice.
