Pretty much everything but the vocals is mixed really well. Vocals could use more makeup gain, dynamic compression essentially, de-essing, and I'm not in love with his performance, but it will only sound worse by hiding it down in the mix and cutting the high mids on it, which is what it sounds like is happening.
More dubs of the adlibs of that's what you're born with etc would have been great to add as shouts.
The vocals can either make or break a song, and in your case they are sitting in a middle ground where they are not quite able to shine. I feel they are pushed off to the right channel for some reason, don't have a lot of chorus/delays to give space, and if they were not in the right channel would sound quite centered.
Beyond that, great chords, great writing, and really catchy!
