The project was made by Character Artist Sean WangYalong.
3D Character Artist and Lead Character Artist at Netease Sean WangYalong has revealed an outstanding portrait of young Hermione Granger, based on her appearance in the early Harry Potter movies. The portrait looks extremely realistic and, according to the artist, it took almost 90 hours to complete the project. The character was sculpted and modeled in ZBrush and Maya, textured in Substance 3D Painter, and rendered in Unreal Engine 5. The hair was made in XGen and UE's Groom System.
And here's the work-in-progress timelapse:
