I heard that if you put pens in the freezer, you can lengthen their life span. I tried that and it seemed to work, I was able to color in 3 of the 5 heads. 1 head has to be redone and the other needs Pure black pens.

So, here is an inked James's head with his fursona holding an IV and in scrubs. The scrubs will be pink.

As for the head, due to I only have 1 brown pen, it was really hard to doodle in his hair, but I still think it came out okay.
