That's good that you don't have those annoying ads because it mostly annoys me and stops me to watch those tutorials if there are ads popping out because of monetization. I don't want to stop you from making money from your videos but most that I'm watching are really too much. I don't want to see also some plain backgrounds and text, also try to add some relaxing and good beats for the background music so while we are listening to your tuts we are grooving.
There are so many easier ways to make money, like a donation spot in the description or a ref link. ( not saying I will be doing that ) I will not have any pop up ads though. I will try and make some music, that is a good suggestion. I am not amazing with graphics and in order to get someone to work on all my videos I will need to get a following, so as the channel improves so will the videos.
I'm not stopping you though as it's your own video and not that really much people who are signing up through given links on the description section of your youtube video. You don't have to be good in graphics or sort of editing, you just have to make the background light and not annoying to the eyes of the viewers and just put those sounds that are quite attractive. If you won't be using your voice you can use this
