Sorry my dear artist, that hand size is a child's if compared to her face/head size lol. Drawing tip: At least, if you need to measure a hand-to-face length ratio, it should be from chin/wrist up to the middle of the forehead (or a few cm above the eyebrows)/fingertips. Of course there are smaller & bigger hand vs smaller or bigger face/head, but on average, it's always the chin/wrist to forehead/fingertips.
