The biggest advice I can give you right now, is to stay away from that basic chord progression. Everyone uses it and it is very boring to listen to. Learn some music theory, play around with different chords. It will do you well.
My last point is that the mix is very loud. Everything does not have to be played at 0db, otherwise things get cluttered. Duck instruments that are not important.
Keep practising. Don't try to be like everyone else.
Could you review back on my song? Criticism is appreciated.
Please contact me if you would like to use this in a project. We can discuss the details.
