Simone Ewenz aka Haascore created this girl with a half skull and half fleshy head.
Of course, we all have skulls and skeletons below our fleshy exterior. However, this speaks to the duality of life and death. We could ponder what the point of our lives are, when death is inevitable and our ends are unknown. Instead of going down a philosophical path, do what you can in your life to make yourself happy. When you're happy, your perspective is brighter and you cast positivity on others. Live a way that makes you happy, and you will truly live. Life is too short not to.
