Portrait drawing with pink and blue ball point pen, i just ran out of pink color

Hello everyone, i am here to share a new portrait drawing with you all. As you have red in the title that i ran out of pink color. which is why her hair looks a bit weird. I guess the hair is weird generally without me messing it up with color. I didn't realized for so long i was drawing with that single pink ball point pen and didn't occur to me to keep a spare one.

Unfortunately they are not available in the shops that are close to me. Might be a while since i get another. This time perhaps i will buy a few extra since i am really enjoying this.

Here are some process shots:
