I made this last year in clip studio paint (for my artfight profile).
Its of my Roblox Avatar in a summer outfit. I normally use toon boom for animating, but decided to try out clip studio (It only lets me use 2 seconds though).
Thoughts? (its small since the icon needs to be 100x100)
Something you can do is make the avatars actions a bit more human like instead of just moving the hair and clothes. Maybe you can use 1 second of the 2 seconds to make the avatar close its eyes which would make it looks like its blinking…?
