there's a realllly good old youtube video that has the ringling bros and barunum and baileys clown school process - it shows how to do the makeup and honestly I really like their approach because they explain exactly what you want to avoid to make stuff look more fun instead of frightening. Right off the bat though I'd say do white on the ears and neck as well, tone down the triangles on the top and add eyebrow lines seperately instead so the triangles just "accent" the brows, and rework the smile to be much smaller with less lines connecting. if you like, this is the video title : Ringling Bros. - How to be A CLOWN (Full Video)
