There is NOOO way you are a 4. You are at LEAST a 6. Last pic is about about 6.5 - 7. These people are high.
But I will say this. Take that black lipstick OFF. Makes you look like a zombie
Brutally Honest Person here, I would rate you at least a 6-7.4%. You have beautiful and attractive facial features. I would say it's how you style yourself. I don't think it suits you. I think there's room to improve also, Jawline exercises, facial slimming would work wonders for you. More jewellery and bling to enhance your appearance. So far, you are gorgeous! <3
