I viewed your most recent video, as a fellow editor I can see the effort you put into your video! Congrats! My only recommendation is not to upload as frequently (if you do). There comes a point in every YouTuber's life (whether they realize it or not) where they have to decide between quantity or quality (there is an exception which I will get into later). You my friend seem like a person of quality. To help with this you literally have to carve out time to edit. Set aside sometime daily where you can work on your video bit by bit and by the end of the week your video is ready for upload!
as I fore mentioned there is a way to have both, and its to have someone else edit for you/hire them to edit! I kept this till the end since this isn't a valid option for most people as they are a pretty small channel, but in the low chance that you do have someone who can edit, or possibly meet someone who is willing to edit for you in the future, I wanted you to be aware of this option.

Goodluck!
