Dynotopology head sculpting

I started sculpting this male head using dynotopo but I cant get the eyes right and the lips doesn’t look right either, please give me some advice like which brush works best for certain areas of the face. I mostly use the clay strips brush… I Also use a Wacom bamboo tablet.

Here is the blend file:

Here you see a good timelapse of a head sculpting. If you stop the video at the eye part you see the brushes and the setup he use. Also you will find more sculpting timelapses there.

Thank you so much, I was definitely hoping for something like this…
