For a first video, it's really good. The camerawork is really good although I wish it was shifted slightly to the right so the gaps between the table and the edge of the screen were the same on both sides, but that's me being really picky. Apart from that it's good. Sound quality was good, I could hear you all clearly for the most part and the intro was nice
In terms or critiquing this I have a few things:
- Title:
I didn't really like the clickbait. Honestly I think that 'Fun Coca-Cola Experiments' or something like that would have more than sufficed. Maybe it works for other people, personally I think it spoils it a little bit
- For your replays you could have had some text in one of the corners which says 'replay'. You don't need it,I just think it would be nice. Same could be said for making the screen gray-scale during replays
- The writing in the thumbnail could be a bit bigger but maybe that's just me
All that being said. I really do think it's a good first video; a good place to start
Edit: I've just seen your thumbnail for your second video. I don't really like it. The colours clash and it's hard to read the text. The base design for your first video's thumbnail was good and you should stick to that and personalise it for each video you do in my opinion
