First of all, thanks for the comments. I appreciate them.
About the arms, I wanted to add a sway to the whole body and then settle it down before the next loop, but the characters in the background are not rigged, they are just duplicated geo so it wouldn’t slow down the scene. And to add the sway to the two rigged characters and not the others wouldn’t work, right? I admit that I feel it was a bad decision now, but I think the whole scene is working as is and it would be a lot of work to replace those characters, so, I’ll leave it like that for now. Maybe I’ll come back to work on it again someday.
