A Doable/Reasonable/Achievable Animated Short that probably takes place on a train

It’s late… so I will keep this short and hopefully be back to elaborate; let dive in.

I have been dabbling in 3d for some time. I originally had interest in game design and was hoping to outsource all artistic endeavors. After a lot of dead ends finding someone to create 3d models and animations for my projects, I decided to learn 3d modeling and animations. After a few years of fumbling around in maya and I started to develop an interest in 3d modeling; here I had come to enjoy that which I hoped never to do. Later I found blender and it’s been cake since 2.8… I have lots of big Ideas, but I am putting those away so that I may create something that is within my ability. I have a few unfinished scenes that I could easily toss together and be used to stage my short film… more later. I am looking for help and criticism. Right now, short story ideas, probably taking place on a train or in a tree house.
