For those interested, I mainly used the Wet Brush. For the hair I used a modified version of pipo's hair brush.
The original piece is 6748x12000.
By the way, as someone who has dabbled in HSLS shaders before, I'm very much looking forward to the next update

Edit: I earlier wrote that the hair brush was based on MANINMACHINE's, it was based on pipo's hair brush.
