A lot. Unlimited.
I will share a mult-figure idea with you:
You can turn your hobby and skills into highly successful online business, providing value and actually teaching people how to do 3D design :)
You can teach techniques, skills and even recommend software products through affiliate marketing (That's the best, because you don't sell, you recommend ;)
You can record a step-by-step course and automate the process.
You can build a funnel which looks like this :
I guarantee you that people will go for your course instead of paying thousands for expensive design school.
Let me know if you need help, I can guide you how to structure something powerful :)
I also attach a pdf guide book so you can get some more ideas.
Hope you got value.
