Ur channel art is pretty good, but i think there is room for improvement. As for the videos themselves, i think you need to have some sort of intro that will characterise ur channel/commentary style. The thumbnails are pretty basic, but for example the infinite minecraft tunnel one looks good, which contributed to you gained lots of views on it. I think you could improve audio quality too, what mic do you use btw? You also need to fill out the description with more text mate. The video qualiy is fine, and i found the content i watched interesting but tbh i aint really into minecraft so couldn't really tell if its better than the average minecraft youtubers. I think there is quite a lot of room for improvement, but you are fairly new so don't give up

Hope you take this constructive criticism on board mate
