Bonjour, OP. You seem to be doing quite good actually, and, in order to help you a little bit, may I suggest a handful of videos from Chris Legaspi? He's an instructor at New Masters Academy and has written books about figure drawing, and drawing faces, which is what this post is about. While you may or may not decide to buy the latter, he's got a Youtube channel too, from which I recommend you watch the following videos:
How to Draw Better Heads, Faces & Portraits (Shape and Design method) (1h24min)
How to Line up Facial Features (Eyes, Nose and Mouth) (1h22min)
How to Draw Features in Any Angle: Part 1 (1h43min) - Part 2 (1h06min)
How to Improve Likeness in Faces and Portraits (13min)
Just to name a few. There are lots of videos on his channel about drawing faces, much more than I have listed above, but those are a very good start, and if you feel like it, I suggest you watch his other videos. Good luck and have fun.
