you lot are aceeeeeeee
Anyway, the first thing is that I would add some sort of very short intro screen just to add a bit more individuality and identity for your videos. Secondly, I would try to improve the lighting as it is a bit dark. You can try to bring any floor lamps you might have around the house if you don't wish to purchase any pro lighting. Otherwise, you can do a bit of colour grading to get the filter just right. Next, the transitions could be a bit slicker, I really like it when the sound of the next clip is played momentarily before the current one ends. This increases the pace of the video while also providing a better context for the next part of the video, making it feel a bit more continuous. And lastly, maybe some background music could be nice, but that isn't essential. Again, I must repeat that I love your channel as it is, so you don't really need to do any of that, but they are just some ideas that could slightly improve the editing aspects.
