Hey Tahlia!
Just checked out your channel.
I like to go by the numbers, so here I go.
Thumbnails: I have absolutely no issues here. They're interesting and far more eye-catching than many of the big Youtubers out there, so you're set.
Production: It seems fine. Maybe later on you could get a camera with a tad bigger resolution, but this can serve your purposes (shoe0nhead got big with a potato cam). The only issue I have are the jump cuts, but I'll comment on that more in the next segment.
Presentation: Well, you seem to be an interesting person, and you have charisma, so I don't think that YT would be a problem for you in the long run. Now, I'll be honest - I think you talk too fast.
Now, this doesn't need to be a problem at all; perhaps that is something your subscribers like. I checked your milestones and it seems that your sub count is on a steady increase. I suggest you make a poll within a video (via cards) and ask if you talk too fast. I don't mind people talking too fast, but I do have an issue with it if I can't understand what they're saying. You don't
need
to
talk
too
slow
- just bring it down a notch. Again, and I can't overemphasize this enough, this is just me and it may be something that the fans just love about you, so you're better off checking it with them.
Regarding the jumpcuts, I know that a lot of YouTubers use them in order to make them seem fast paced, and you're like that anyway, so the conversation seems dense (not dense as in stupid, just... dense
).
I think you're entertaining enough and that you have what it takes. Just keep going at it and you'll be fine!
