More resin to increase the hair volume.
Some major chipping and filing to smoothen her hair part.
Resin mould applied to the chipped hair part to give her that neatly-kept-hair look.
A layer of resin for the eventual paint application

Custom sticker/decals for her school badge on the sweater.
The final look and its perfect.
