I've made 4 videos for now and getting better at setting up the sound and video quality but I feel like I'm not quite where I want to be

I am looking through some smoking pipes that I will later try to restore and repair so for now each video is simply looking at pipes and rating them depending on some parameters

The latest videos that I've made (and will make) only look at 5 pipes instead of the 10 that I went through in the first few videos

Do you see any critical issues with the videos? I am quite critical my voice, sound and accent but I may be overthinking it.
