I'm a bit too lazy to really break it all down but here are a few things.

Your voice is much too loud and muddy in the intro.

You sound funny when you say "shawty". It doesn't sound natural at all. It really sounds like you're trying too hard to say it like that. Let it come out naturally like you're in a real convo.

The flow on the second verse is much better than the first. The first is boring.

Voice on the outro is muddy too.

And chorus is bland...add something to it.
