generally, you want to have more views than subs. Most views come from subs, but you want to make sure you are reaching new people as well. I would try to get your audience more engaged in your videos. I know I don't have a lot of subs currently, but I generally try to keep my views double my number of subs at least as a general rule of thumb. Also, I would keep an eye on your youtube analytics. This will definitely give you some insight as to where your views are coming from and how long they are watching your videos.
