R4c7 not sure.. but probably not unless you're allowing those diagonals. I think to avoid it will be a challenge.
Vagrant, I'll start something from scratch; good idea. Now I just need an idea of WHAT to make, & give it a try. (no diagonals)
Update:
I left some single pixels on purpose but only when I really felt like they just looked better; I will probably scan over it and mess with it more later with rested eyes:
For example a couple of the curves just seemed to need single pixels and two of the stars have an intended singles.. there are probably a few here and there elsewhere. I was so delirious last night when I posted.
UPDATED again.. No Singles! ('cept the two black outside of the oval outlining the hair)
I was really daunted at 1st but I'm really glad I tried this.

Dang it.. there are still a couple singles in the hair here and there.
