I couldn’t replicate those videos as I’m not a 3d designer/animator, but they extremely look like some very beginner stuff done after watching few tutorials on youtube.
I hate to be this person, but someone has to say it.
The stories they tell are maybe fun, but totally unclear without the caption.
The ligtning is strange and unpleasant.
There is a thing called 12 basic principles of animation, those videos use none of them.
The simplicity of the enviromnent looks more like lack of resources than clean minimalism.
Don’t get me wrong, you’ve done more than 99% of people wanting to get into 3d animation and you can/should be proud of it.
But look at Maidsafe, they working on their product for years and are still not ready. Good things need time, failure, and starting over and over.
If I can give you some advices there they are: educate yourself, get feedback (maybe on some 3d design / animation / story telling forums), work with smaller companies/individuals who indeed would need your help, get connected to people doing similar things, talk to them, grab a beer or something with them. Allow yourself to fail, get some short and longdistance goals and change them if needed.
