Overall I was very happy, despite some joseki mistakes early on and (as per usual) some terrible endgame I played well and more importantly I enjoyed it!

I certainly think the main point for me to take away here is to think longer and harder about the early middle game. dropping a few one or two point moves isn't the end of the world at my level but making 10-15 points mistakes is seriously costly!])
