Lips #Procreate

This are my first "real" lips in Procreate :).
It takes a bit of time to layer and blend... patience is needed for a nice outcome :D. Nevertheless I am happy with the result.
The part that I found the hardest: where the upper lips goes into skin... I had always like a hard line. At one point I was like "merge the layers together" (I prefer separate layers) and then I smudged this area (the upper lip and the skin) so it blended better.
Thanks for the course!
