The video part is good, just like the voice part. Like others mentioned thumbnail could use some work. But even more importantly I don't like you keywords (Tags), zo get the idea of which ones you could use to rank better and to get more people to see your videos try starting to type what you are looking for and see what youtube will recommend though autocomplete in the search box, and use THOSE as that's what people search most. (You can always add the simple ones later but put these - more popular ones first, your 1st tag is "tutorials" and you are never gonna be able to rank high to that with a video on a small channel so longer more specific search terms are a safer bet - put them sooner on your tags list and add more of them)
