consider using your core more to actually have some power in those turns... they're super flicky and it looks like you're largely surfing off your hips/ legs. Learning to effectively ride a wider range of boards would likely help you w/ that because you'll learn how to push through water much more effectively and with a great deal more power, as well as surf the wave from a whole bunch of different angles as opposed to just surfing the board.
Not meant to be a dig at you-- I see this in a lot of guys who learn a bit later in life, who move down to the newest HPSB way to quick because they don't want to be that older guy who looks "uncool"... but they end up majorly handicapping themselves in the long run and never really end up smoothing out their style
