I think you sound great. It didn't sound like you were putting a lot of effort into it though

Sounds fine
Tone and pitching is good, however you have some articulation problems.
It's nothing that can't easily be fixed though.
But it depends on what you're going for. As the others said, to really know if you "can sing", we'd need to hear you in a broader variety.
For most singers, it comes down to their mix.
