good job brother , i see your audience is old and use tv , be sure that your banner and everything is optimized for tv , also i see your subs are growing slowly , this i think because people who watch from tv and old people dont know or find difficult subs to the channel so be sure to remember the viewer to subscribe telling them how to do it , in a short part of the video maybe in the middle.
also dont stop publishing now , more you spit out content more your best view video will get recommended probably you will reach monetization likely for this video that are getting very much views , also dont forget description and tags and engage with comments !
