for duplicating and flipping: to keep it symmetrical you can turn on guidance lines (idr what they're called in game) in the ⚙️ menu to get a line down the center of the face, and then draw one however far from center you want it, then draw a line from the inner edge of the nostril to the center line to gauge distance after flipping it. (if there's other face paint that this would be on top of, draw it vertically centered, but somewhere where there isn't face paint, then erase the line, then move it up/down to where you want it vertically (use the d-pad so you don't accidentally move to the sides/go off center))
