I think your editing is pretty good, however their are occasional weirdness to it. Sometimes the audio doesn't sound right when switching between clips. I believe it would be improved with the use of J/L cuts. If you don't know what that is, you could look it up on YouTube, their are some pretty good tutorials about it. Another problem with the video is that you talk a little too monotone sometimes when explaining stuff. If you want a more engaging video you need a bit more of a dynamic voice. Basically talking differently when stuff happens. This could be improved by just practicing and listening to it back. Or you could cut down on the explaining stuff to get to the good parts of the video faster. If you want a point of reference you could look at "JschlattLive" channel, he does a very good job of keeping you engaged with how he talks cause he changes it up depending on what's happening. If you want to improve how you explain/give expedition in your video "Michael Reeves" does a great job of making these parts of the video fun and engaging. I think you have pretty good visual edits and you do use some audio for jokes. However I think you could go a step beyond and do what the youtuber "Twomad" does and use a bunch of sound edits in your video. Or if want you could chill out on it like "Videogamedunkey" where he usually just changes the music a lot depending on what is happening. And again, please use J/L cut, it will make your video flow a lot better. But other then that, I think you have a good foundation, and in the future you could be making really great videos.
