Portrait drawing with ball point pen || Warming up for the day

Hey hivers, i am here to share a new portrait drawing. Most of the time when i want to draw something i start with something simple. Something i know i can draw very easily and won't mess up like eyes or nose or lips separately.
I do those sketches like a warm up before i get into a drawing properly. Today however i drew an entire face, there were actually several but i am keeping that page for later to share.
This started as nothing and then i put a little time and ink into it. I have to say that drawing hair is exhausting.
Anyway, i think it turned out okay.

Here are some process shots:
