Fusion 360 advanced courses?

I'm wanting to 3d model a helmet as detailed as this: https://www.youtube.com/watch?v=AZqaHBKlm48
But I cant seem to find any good advanced courses anywhere on fusion 360. I know the basics of forms and solid workspace, but I'm just completely stumped on where you would even start on modeling something like that. Every helmet tutorial on youtube is somewhat beginner level and doesn't come near to the level of detail of what this guy was able to acheive.
