I would encourage you to learn to sing properly before you try that breathless whispered thing.

Your timing isn't great (on singing or guitar). But honestly you just sound like someone who hasn't really put work into technique, and so you're hiding behind the fact that your only sort of half-singing. You sound better when you come closer to full singing.

But this feels like it's relying on the gimmick rather than technique - so learn proper technique, learn to sing properly with your full voice ... and then come back and try something like this and it'll have a lot more meat to it.
