Blue ball point pen portrait

Hello hivers, i am here to share with you all a new portrait drawing i did today. This is a portrait of a man with very lite features.
In most of pen drawing i only use regular ball point pen but drawing hair with that is very hard so i used a gel pen which is much darker than the ballpoint pen.

Let me know your thoughts about this drawing.

Here are some process shots:
