The new hair had to look like the original, but no longer made of indestructible hair strands like Zero's (I'm pretty sure they keep shining beautiful and intact no matter how much damage he has taken), so I got some inspiration from Pallette's mechanical hair. I'm glad you like it!
Mechanical hair is very neat. It gives them a much more artificial look even if they are shaped alot like a human. Pallettes hair is amazing. Good inspiration!
