I've been trying to figure out how to draw freckles, as shown in picture above ^ and I think I'm doing alright, but they still don't look entirely good.
Also, hair, this character's name is Winter, she dyed her hair white a long time ago, and over time it grew out to be this half black half white look, and I'm not entirely sure how to colour the hair so it actually looks good.
Then there's the mark on her face, I really have no idea how to draw scars. >.>
