Someone on here mentioned that Jonathan said a while ago he's doing some design/animation work on the side now because the money stopped rolling in. I don't believe this for a second. He completed Uni over a decade ago, in a field that's constantly evolving, from looking at this vlogs and 'work', I can't see anything anyone would be willing to pay for.
The animations he did for his channel ('Dancing Baby', 'Robot' and so on) all looked very amateurish, the more professional looking intros for his channel were all done by actual professionals he had to pay, everything he does himself for the vlogs is extremely basic, you see influencers half his age put out more professional looking videos and edits. Heck, Judy from itsjudyslife, who's an amateur, does way more appealing vlogs five days a week.
He may be a 3D animator, swim instructor, electrician, stock broker, nightclub dancer, cashier and whatever else he claimed to have done professionally, no one in the year 2020 will pay him to do design or animation work for them.
