Ball point pen portrait [2] smile

Hello everyone, i am here with a new portrait drawing with ball point pen. Unlike other portrait drawings of mine this one has a little bit of emotion in the face. Not just flat looking robot face that i do most of the time.
Drawing this was very much fun and the ref image had amazing shadow and contrast to work with.
Although the hairs took all the energy out of me. That was exhausting. But worth it at the end.

Here are some process shots:
