I think that depends a little on what you would define as 'having success'..
Like, this video had untill now about 110 views..I have been at drumclinics from kinda famous drummers where were a lot less people..
If you would define 'having success' as having at least 10.000 views, then yes, i would agree that you are not having much success..
Personally i am not a huge fan of vlogs, but compared to the ones i saw from other people, i think there is not much wrong with your videos..I mean, your presentation is nice, your playing too, etc..
Maybe there are just too much vlogs nowadays to really stand out with something..
If you would like to get more views as a drummer though, i would advice to make drumcovers from very popular artists, drummer-songs, etc and put the artist/song in the video-title..Disadvantage in that case is, that you only get the views because of the famous artists name..But still, maybe you can create more followers like that..
All that being said, my advice would be to not focus at all on views, likes, etc, because in my opinion all those things belong to the category 'most superficial things of modern life'..
