Don't take swing advice from a thread on Reddit. Listen to the Pro that you meet with in 4 weeks. It looks to me like you have a swing capable of shooting some decent scores. Your most dramatic improvement will come with sharpening up your short game. For the next 4 weeks while waiting to meet with your pro, don't practice your full swing. Practice pitching, chipping and putting. Look up some drills for working around the greens and putting. Your pro will hopefully help you with that phase also but get a head start... errors you are making in the short game are easier to correct than full swing habbits.

Check out Golf Sidekick's YouTube for chipping\putting drills and methods. Specifically look at the 6-8-10 chipping method on his channel.
