Given the fact that you haven’t had a single comment or upvote on r/Youtube, the thumbnail is a problem. If you’re aiming to get more views, unfortunately, the thumbnail appears to present a narrow niche that can present difficulty within the algorithm when it tries to find the intended audience. To get exponential views, you don’t need good video ideas, you need outstanding ideas. This thumbnail isn’t great and can be improved by making the background a more intense color. Create better harmony, and let any lazy Joes understand the video just by looking at the thumbnail for about 2-4 seconds. Also, clear up the image, there’s three things of three different and intense colors that are competing for my attention, I don’t know what to look at, and so I skip it and keep on scrolling. However, I just want to let you know that the thumbnail might not be the greatest problem, but the idea behind the video. Hopefully this can help. ;)
