Yeah! Having a follow up course would be awesome. Which is why we have playlists…
Take a look at the TRACK: Modeling in Blender – 101 playlist, if modeling is the direction you want to go.
Pothead is a good choice after Press Start, and also the SESSIONS series would be a good choice.
So far I have recommended a few modeling examples, but you may want to go in a different direction and learn more about materials and shading, lighting, or rigging and animation.
Yes the instructor could suggest similar courses, however they may not be what every student needs or wants next. With new course continuously in development, and subsequently released, those needs and wants change too.
What course you need or want to take next is a personal choice, if you haven’t already done so, the fundamentals playlist is a must watch. Keep an eye out for the release of CORE, coming very soon, the updated and extended series of fundamentals.
