In the future I would ask that we maybe avoid posts that act as a promotion for our competition. That having been said Morning Fame are good people and we can allow it, but's stick to the topic and not the tool.
You are below average in the number of subscribers that you have compared to the number of views, the watch time and the amount of engagement that you are getting. This is a simple case of you needing to improve your Subscription Call-To-Action. For best Subscription* results you should put this CTA in the first two minutes of your video and you need to come up with a fresh, compelling approach as to how you are going to convince your new viewers that they need to subscribe to your channel. The generic 'Please Subscribe to my channel' rhetoric is getting old, and creators need to get more creative when it comes to convincing viewers to subscribe. You should put some focus on this.
*I personally take a different approach for subscription results... subs matter far less than watch time and AVD. As such I typically put my subscription CTA's towards the end of my videos. While you will get more subscribers if it is placed at the beginning of your video you will inherently pick up more passionate subscribers if the CTA is at the end of the video.
