Onyxdime maybe you can give this suggestion to ICSTOR. His issues with completing projects aren't rare. Lots of projects start off with a bang, then get bogged down later as the people doing them flail around aimlessly, with no direction.
What he needs to do is apply some software engineering concepts to his work flow.
When he comes up with the idea for a new project, and works on creating the characters, etc, he should write out a high level overview of the whole story. He should decide what goes into each update at the start of the project. If he wants to keep the voting thing going on Patreon, he could vote for which side girls go into which update - honestly, they're pretty interchangeable, from an update perspective.
Design, then code (render, whatever).
He should also work more like an assembly line - do a scene, then send the renders for that scene to you and the coder to write/code that scene. That way you're all working in parallel, instead of sequentially.
If he has the full design fleshed out up front, he'll have goals to hit for each episode, and know exactly what needs to be accomplished.
