I apologize ahead of time for saying this.
Forgive me for not knowing the name of the program you use to make these animations, but I don't like it.
Everyone looks unrealistic and robotic. Bordering on that animation term "the uncanny valley".
My opinion is that you've got a lot of potential with your stories, characters, and animation skills.
You should use a different program to make these animations.
Ones that professionals use like flash, maya, blender, after effects, etc.
Even 2d hand drawn would look good.
Maybe you already use these programs, I don't know.
But this looks like the same program they used to make the 2016 BERSERK series. (Which was shit.)
I can tell you got a lot of great ideas and talent,
just please use different software. (something better than this)
