Hello,
You're very talented with 3D design work, I'm learning basics with Tinkercad and Fusion 360 for 3D printing, but what you're doing here is next level, very impressive.
Sounds like Ipad has some nice tools for design work, I'm primarily an Android user and was not aware of Apple having cutting edge design apps like this.
I will give you a follow because I'm intrigued by your talent and want to see more. Thank you for sharing!
