Others have pointed out some negatives to your approach, I'd like to point out something else thou, which comes from 30+ years of work, changes of career are always risky, said risks can be mitigated (to a degree).
A way NOT to mitigate the risks thou is to take a break (1 month long holidays) right after starting a new chapter of your working life/career.
Everyone needs breaks especially to clean up their minds and (re)build "stamina", but said breaks have to be taken BEFORE the new project/life phase starts, not right after its beginning.
As an example you "promised" 2k renders for every update and an update every 2 months, your first month was 285, no biggie issues happen and the start is always rocky, your second month thou just ended and you are going on holidays, the first update will be in January, so possibly 4 months after you started working on it?
You are already 2 months late on a (self imposed, but publicized) 2 months deadline, working on your own/self employment doesn't mean you can be more relaxed on deadlines, quite the opposite, as nobody will pick up your slack, unlike let's say in an office or team.
Best of luck to you
TakMycket ,
I really wish you the best (because I like when creatives succeed) but this is starting to look like a disaster (for you) waiting to happen.
