I really admire the look of the animated trails and smoke seen in this video. It feels very stylized and clean, yet hand drawn. I'm wondering what tricks are used to make it more efficient in a production environment? I feel like using masks would be cumbersome. Maybe vector paint in some cases would work. My guess is these artists are using something more suited to cel work like Toon Boom or Anime Studio. Just looking to incorporate things like this into the fast paced turnarounds we deal with at my work.
