Hiking among Plum Blossoms

I searched online, and it seems to be a matter of opinion whether "among" should be capitalised in titles, but to me it looks strange uncapitalised, since it's a longer word. The rule that seems the best to me is to capitalise any word that is 4 or more letters.

This time it includeds my English narration.

You should use present tense here because you're telling us what the video is like (notice: "is", present tense). If you use past tense, it sounds like the video changed, like it had narration in the past but doesn't now.

Also, this sentence is grammatically correct and not unnatural, but a bit more natural way to say it could be something like, "This time I included a narration I did in English." I wrote 'included' and not 'includes' because you made the narration in the past!
