Groom artist Julie Guillerm shared her work on Jinx/Powder's hairstyle from the alternate universe in Arcane. It was her last groom during her internship at Fortiche, the animation studio behind the show, and the recreation of Alexandre Dobrenel's hairdo turned out so great that you can hardly find the difference.
"It was a very good exercise that taught me how to reproduce an existing groom as faithfully as possible."
To make it look complete, Guillerm used Houdini, Mari, Nuke, and Guerilla Render.
She also practiced on Lest, Viktor, and Caitlyn, and you can see these and other projects on her ArtStation.
