Hey Kaitlyn, I jumped into your channel. I'm not the best to offer critique on the actual content, so I will offer what I saw elsewhere. Channel title, and photo looked good. I would shrink your intro video, but otherwise +1.
Kinda in the same boat a JRuncle, I'm no expert on makeup channels haha, but I do think your videos have nice quality at least visually. The camera records good quality, and you seem to have a fun and nice personality that goes well with the style! Your channel artwork is also very nicely made, some of the words on the thumbnails are a bit hard to read, but they're not too bad overall! Again, I can't say much about the content itself, but from an outsider's perspective, I think it's really well-made!
