Reviewed Channel Feedback

You could upgrade your banner and your logo. But they do look good, so dont be too worried about that.
You need better thumbnails definately. Try getting a thumbnail preset
Your titles are good as they are. But if you want the title to look interesting you could try adding OMG SOMETHING AMAZING | Minecraft SkyBlock.
Great to see that you have some playlists set up.
You really need to update your about page, so people can know more about you when they visit your channel.
