This tune has a nice, open sound that is balanced and well panned. I can hear the low end very well, and overall the mix is smooooth. When you say that you are using "pop progression" chords, does that mean you're not writing this song yourself? BIAB? If so, I would recommend that you take a stab at it yourself. It's one thing to have good mixing skills, but quite another thing to have good writing skills. Keep us posted.
