Found this over on Sketchucation in a post by Pilou — in my view it rivals anything produced by major VFX studios — check it out:
The CGI is incredible — with some of the most beautiful world-building I’ve ever seen — and all the more impressive since it’s primarily the work of one 3D artist… and all done in Blender. (It took him 3 years to produce this 1st episode, but once you’ve seen it you’ll understand why!).
Awesome film - it’s even better if you’ve watched his Lazy Tutorials because they show exactly how he created a lot of those effects.
Super cool!
I didn’t actually know of Ian’s work until coming across this film, but I searched out some of the Lazy tutorials afterwards — since they were referenced by so many of the YT commentators.
Maybe it will be a prod for me to finally execute my never-quite-implemented plan to fully learn Blender 
By the way Justin, I appreciate all your efforts in producing such great educational content for SU and Blender!
Well it’s a big program for sure - focus on the stuff you’re really interested in first - it’s super easy to get sucked down a rabbit hole ;p
Glad I could help!
