Great to see more posts in this section of the forums! I know getting feedback can be hard at times what with the lack of people running around here heh. Really like your YouTube name lol very easy to remember and rather unique.
With that said I do have a few tips that you may want to consider; Remove the intro. This is just my personal opinion but all of the very popular Let's Players (whom I watch, such as CaptainSparklez, UberHaxorNova, etc.) don't use intros and when you wanna watch a bunch of their videos in a row and they all have the same intro, it can get tedious watching it over and over. Luckily though, yours isn't too too long, however I would consider removing it and leaving it for special videos and out of your Let's Play ones. Perhaps keep the intro on the very first video of a Let's Play.
Also, the way you talk, it's as if I'm watching a walkthrough or a 'newbies guide' what with all the tips on what's gonna happen next and how Sleep Powder isn't 100%. I'm not saying it's a bad thing, I actually think it's good considering I don't hear that type of speech too often.
One thing though that I do have to admire, which I have to practice myself more, is how good your annunciation is. I am still new to Let's Plays myself, and my annunciation isn't the best, but hey that's what practice is for right?
Anyway, I wish you luck on your journey. Especially your nuzlocke challenge lol.
