I was thinking about my old OC’s and a lot of friends are doing revamps of their old OCs so I wanted to do the same and it really helped me feeling better about my art. Those are OCs I created when I was about 18, I think. The brunette girls name is Chloe and I think the blond girls name is Ash. They were designed to fit in a story I had in mind back then. They used to fall for two different guys but today I noticed that they are way better off with each other :) Ash is a Rebell and Chloe is more mature than her other friends but I think they balance each other out just nicely :)
Honestly, it's probably the shape of the face and head that gives it away--I just haven't seen the particular combination of features together anywhere else!
