Any tips on how to play Shooting Guard?

I'm 14 years old (male), and I'm going into 9th grade this fall. Currently I'm playing Shooting Guard for my Summer BBall team which is grades 9-12. I'm good at driving and a good finisher, also good at making free throws. I'm a decent shooter, but I can miss a wide open shot sometimes. Any tips on how to get better at SG? Thanks
