Hey! I'll just post my review here, don't want to clutter your comments section!
Thumbnail: Looks great, the KFC logo isn't copyrighted right? you checked that you can use it without issue in your thumbnail yes?
And the text is nice, but the exclamation point could have a larger gap between the top half and bottom half, as it sort of looks like a lower case l, spelling "Littel" y'know?
Description: Not much information here, there could be a small/brief little intro for people who want to know more about you, as well as you should include links to all of your social media outlets, such as twitter, facebook etc. While those can be included in annotations it's generally better to include the links in both annotations and the description!
Commentary: Now here's the real issue in my opinion, and while i understand greatly how difficult commentary can be, you might want to include some more cuts of the "stutter-y" parts, the audio quality is fine, but you yourself sometimes fumble a little and repeat yourself, this can easily be cut out and would also shorten your video, which given the attention span of people today, would be useful. What i find helpful if to write a small list of bullet points somewhere off camera than you can glance at to remind yourself of specific topics that will be relevant in your video. While it's not a script, it can help you should you get lost
Info provided: Great review, you gave your own personal opinions, what they could improve, what they did well and a solid review number of 8/10. Applying a number to something like this helps your viewers get the information they want faster. So if it were me, i'd show that section earlier, maybe around half way through the video, in order for people who may be getting bored to see the review number, and leave there should they desire.
Video length: Honestly i think it's a little long for the actual content of the video, but you sped it up nicely at points to shorten it to, while i wouldn't put music there along with it, that entirely up to you. In all actuality though, you could do this review video in under a minute! People are often very busy, and won't mind you heavily speeding up the parts where you are eating
Plus you could do a series of "Speed reviews under a minute" or something like that. Which would draw in more viewers.
I personally thought it was a decent video. But you could do a little more to improve it, but the camera quality is great!
