At this point, even if you balanced your talent points you should still be okay.
Besides, that's not really a bad thing.
Anyway, to get more talent points you either need to breakthrough to another rank (currently Azure rank is a story related breakthrough and is inaccessible), or you can do training. Training will give you limited amounts of talent points.
You can also master enlightenments, which generally give you talent points as rewards, perks or other benefits.
