Hi Brian, What is the name of the tune you´re comping to, please? I think you´ve done a great job playing all those chord changes in various rhythms and using the higher end of the piano. All that is difficult to master. When you want to get more flow, try living in the music a bit. You can listen to other artists` performances of the tunes you like and hum along or, imagine you´re playing the part you like hearing and then (transpose) copy it on your piano or, imagine what you would play (instead of what you´re hearing) and play that. I think you´ve done the main work and your playing will evolve when you keep in mind what you want it to sound like and, hearing what you can already do I know you will succeed. Congratulations on your achievements!
