Ball point pen sketch

Hello everyone, i am here to share a new ball point pen sketch with you all today. i was looking for something to draw that has orange color in it, you know, because i have the new orange color pen?
so this girl had this crazy orange color looking glasses and only one is visible, so i decided to draw her. i tried to make the glass look like three dimensional with some shadow but i didn't have any lighter color and i already had filled the whole area with orange, so that was a mistake.
But the color is the main focus of the drawing and therefore, it looks pretty good, at least i like it very much. i didn't sketch the back of the head,because that is way too much inking. And on the plus side i had a lot of fun working on this one.

here are some process shots:
