I have created another real-time model, this time based on concept art by DHK.

I used wingfox tutorials to learn how to make the model better, especially the face, and used standard Unreal Engine eye, eyelash, and hair material. Creating long, white hair for realtime proved to be very difficult.
I used Zbrush for sculpting, Marvelous for clothing, Topogun for topology, Substance and Mari for textures, Unreal Engine 4 for rendering and Maya for everything else. I wasn't able to replicate the concept art pose very well, so most screenshots are t-pose this time, which left me a bit disappointed, but I learned a lot.
