Why it worked
The video likely worked due to its satisfying ASMR-like visual of the oil pastels being applied, combined with the artistic process of creating a recognizable image. The use of vibrant colors and the close-up shots of the texture created by the pastels would have been visually engaging.
Summary
The video shows a close-up of an artist's hands using oil pastels to color a drawing of a glass of whiskey. The artist applies various colors to build up the image, creating a textured and vibrant effect. The video concludes with the finished artwork and the text 'done :)'.
