Hair stylists, please, may I ask for help?

I did this hairstyle on a recent shoot. The (loose) inspiration was this picture (I realize it is heavily Photoshoped)
I'm glad I managed the soft falling wave around the face (what can I say, I'm grateful for baby steps too

), however, I'm not really happy how shaggy the hair looks.

I know I can smooth flyaways at the top of the head with hairspray and smoothing them with my hands, but how can I smooth the waves?
Styling products I used (all from L'Oreal Professionel): Pli + blow dry (for previous look in that photoshoot), Hot Style Constructor (to protect the hair from heat + hold) and Gloss Control (after brusting the waves) and occasionally hair spray (Infinium, force 2).
Maybe I should have used something with stronger anti-frizz? Or maybe wax?
