Wanting honest opinions on my channel!

I have taken a look and I think your new banner is now much improved! It is clear to see right away now what kind of content can be expected i.e Sims/Pokemon/Minecraft and the cloud theme is pretty neat. It's good that you now have your schedule there but I would say that it is a little difficult to read and I'm on my laptop, so perhaps making the font a little bigger should make the difference as right now the tight handwriting style doesn't help it to stand out much. But otherwise, I think it looks good :)
Try and stick to a certain template with your thumbnails, I've just started a lets play Planet Coaster series and the thumbnails all follow a similar style.
