Digital color on ball point pen drawing, my new favorite

Hello everyone, i am here to share a new portrait painting, digitally colored over a ball point pen drawing. This just became my favorite one. I love how the colors of this one turned out. I didn't exactly expect it but i am glad this happened.
I don't always get nice colors in my drawings like this. So when this kind of things happen i want to use those colors again later but they don't seem to work.
Let me know your thoughts about this drawing.

You can take a look at the process shots to see how i colored the drawings step by step.

Here are the process shots:
