How can I actually improve my curls? What am I doing wrong here?

This is day 2 and about to give up on my curls...

My routine: I used Living proof frizz shampoo, briogeo conditioner. Then, lightweight leave-in (its a 10), curlsmith flexi gel, and mousse (not your mothers) on wash day. I air dry with a shirt (sometimes i diffuse it), slept with a satin bonnet, and this morning I only added a bit of oil. My curls lose definition overnight and turn frizzy/puffy instead of staying soft and defined. What should I change to get better results?
