Hobby project: a lightly animated comic

I am using VRoid Studio to create characters, load them into Unity, and am trying to create a little lightly animated comic, using the web stories format (https://stories.google/). By lightly animated I mean I am not trying to create a full cartoon. This is just a hobby in my evenings. I am trying to create more like a comic book with speech bubbles for text, but where the frames are animated a bit. I have been collecting animation clips to use in Unity, but found that reusing the same walk etc clip for each character reduces the individual personality of each character. So I was having a look at Deep Motion to see if I could create animation clips with more individual personality for the characters. I may end up with using some VTuber software for some scenes that only need head and shoulder shots, then use Deep Motion of full body movement scenes. I am still trying to work out which tools to use.

I am quickly discovering I am not much of an actor however! And I think I need a better lighting set up when taking the videos.
