I see this two amazing ball point pen artist on hive, 
these people are so amazing at ballpoint art that their arts made me try to draw some with ball point pen.
I am not comfortable with this because when drawing i erase a lot, to get a good sketch but in this case i wouldn't have any control after i draw. So if i make a wrong line i will have to draw along with it.
So, instead of going big, i just sketched four tiny heads and put them inside boxes, i actually drew the boxes before to fit the heads in. Two in the left are drawn from nothing which is why they look worse, for the other two i used two of my friends' face.
