You might be a little too close to the work to judge, but to me it still looks off. I suppose I might not immediately think it was AI, but there's something not quite human about it. The video contents are a little too sterile and clean, lacking character. The room is quite empty and the composition doesn't cause me to focus on any one thing. That said, you could probably improve a bit of it with some prompting.

The making-of post itself also is clearly LLM generated, probably by Claude, judging by the language used.
