Simple and clean Ball point pen portrait drawing

Hello hivers, i am here to share a new ball point pen drawing with you all today. For today's drawing i sketched a female portrait and colored it as clean as possible. I would love to have just chunk of colors like the first stage but a bit of shading is very necessary.
Although i did feel like i ruined the drawing a little bit by adding those shading strokes and the blue color.

Anyway, here are some process shots
