Hey, you have a solid start to your channel, well done! I would suggest that you maybe spend a little more time researching your keywords; on your Valentine's Day stories vid you didn't rank for a single term. It appears as though you optimized well for several, which means that they just weren't good keywords to use (at least I suspect that is the case; the other option is that your video performed well and while that is possible I thought the video quality was too good for this to be the case).
I would also suggest that you make an adjustment to your subscriber call-to-action. You include it at the beginning with the introduction that uses that creepy sound effect. Sounds cool, but I would suggest doing a genuine request for the viewer to subscribe with the actual narration every single video. It's more personal. Otherwise it just kinda seems like a leftover, unimportant part of an intro that is going to garner much less attention IMO.
Enjoyed your work, keep it up! You have a cool channel!
