Feedback on my YouTube channel?

I know this is cringe and I hate promoting myself but I guess I need to play the game to some extent.

I have a hiking YouTube channel. Was getting a smattering of views for some hikes I did in the Canaries, then posted a Coast to Coast video and it did really well (for me), then posted another couple of videos and they've gone back to smattering numbers.

I was just wondering, provided you've got some time to spare, if any UK hiking fans would be kind enough to have a look at my channel and let me know what you think? What you think works? What doesn't (nicely, though!)? What you think I could do more of? Should I just quit and enjoy my hikes?

It's here if you're interested. If not, well that's fine too. Thanks!
