One thing all models aced was the costume design. I don’t know why this was the case. Maybe they trained exclusively on lots of fashion data to use models in fashion industry.
Filmmaking is inherently an iterative process. You don’t normally one shot music videos in the real world. Agents should review and iterate at every step of the process. Lots of room for improvement here.
Also for comparison, budget of the original Uptown Funk music video was probably around $100,000. Even “indie” is pretty expensive in traditional filmmaking due to high cost of equipment, people and places. 100x cost reduction is huge for any industry.
