If that is your ambition and goal, wouldn't it make some sense to take singing lessons? Maybe even take some acting lessons, too. That's what people do whose priority is to become a better singer. A singing teacher can assess your talent and suggest the best direction for you.
On a different note, regarding the video: why does one of your videos focus the camera on the total mess in the cellar and not on you, the singer? That is bizarre.
The second video you sing far too softly and without any conviction or projection.
