I did this awhile ago and it was meant to depict a basic design of Lacus's back tattoo and weird glasses/goggles(?)
This is done with a sort of fur henna and it's kind of a tedious ordeal but hey whatever you get your markings for awhile.
I think I was trying to make the background a sort of blue room and failed because MyPaint is weird. Finally figuring out a combination of MyPaint and GIMP.
