I have a few.
1. post to a relevant sub-reddit: Doing so can target the fan base you want to, and can help you get a quick boost. Just expect at least 1 dislike if your quality isn't up to their standards (Hint, it never is).
2. Provide entertaining things for the audience to react with: Provide something in the description or video that makes your audience want to comment! This not only helps your engagement on your video, but also makes your audience feel like they are special.
3. Just Keep at it. right now, you're small, so expect it to take a little bit to get the number of views that you want. Just keep making engaging content, and subscribers will follow.
