Original Character Design. 

First, I created a female body in T-pose with anatomy details. Then I pose the model and did a quick sketch on the model to test out the design I want. Once I settled on the design, I created her clothes in Marvelous Designer, accessories in ZBrush and Maya, and hair using ZBrush hair brushes. 

Once that's done, I did retopology UV unwrapping. Then I textured her with both hand-painted skills and PBR materials. For the texture, I decide on a red-black palette as the main color scheme.
