Five short vertical clips in a Lego Movie cinematic style

I'm Alf — a fractional HR leadership consultant based in Singapore, building my first content series for LinkedIn. I've come across your profile and it looks like exactly the kind of work I need.
The project is five short vertical clips (30–45 seconds each) in a Lego Movie cinematic style, one per service I offer. Everything is production-ready on my end — detailed prompts, voiceover scripts, music prompts, brand specs. The voiceover will use a clone of my own voice generated in ElevenLabs, for which I'll supply a clean source recording.
The main technical requirement is consistent character appearance across all five clips — the same Lego minifigure in every scene. Before we proceed, I'd like to ask: how do you typically handle character consistency across separately generated AI video clips?
I've attached the full brief for your review.
