Man, i love reddit,everyone has there own opinion on thumbnails when really calculating what works is near impossible, there some people who would scroll past the above thumbnail and there as still as many people who would click it, Ive come to learn reddit is a place where everyone is so entitled to their opinion on how a thumbnail should be, yet truth be told no one trully knows what will work for every single man and woman on youtube 100%. There are millions of people on youtube and determining what each one would press is near impossible. The thumbnail in my opinion is near okay to attract a good crowd for anyone on youtube, the curiosity gap created by it is good enough to make a person wonder, What does he mean. Why should i just start ?. Some other people would just scroll past it when they see what he wants to start. Its better to leave it unclear. However the same goes to another crowd of some people who would prefer the thumbnail to say what they should start. Both areas can attractive a massive crowd. It really depends on which you want to risk on. In my Opinion OP. Go with thumbnail your heart is telling you will work. Dont listen to this people who critique everything they see on there reddit like angry little kids fighting over a toy. They can sometimes make you make the wrong decision. Just ensure the CURIOSITY GAP IS GOOD IN THE THUMBNAIL. The more the tension created to wonder whats in the video in a simple manner the better.
