Your Home Page:
Your logo is awesome and eye catching but I noticed that your banner isn't really up to much, it looks really cool and I can see you've added several games into it, my advice would to maybe added a couple of links to social media or at the bottom maybe add what days you upload etc?
The only playlist you have on your homepage is "Uploads" you should add different playlists to your homepage maybe things like "Funny moments" "Garrys Mod" that way it will be easier for people to find out what kind of things you do on your channel
Thumbnails:
I have noticed that on most of your thumbnails, the text isn't really that clear, some of it is quite small and plain but that can be easily fixed
Videos:
You have great quality videos and I find your rage videos really funny XD one thing I would say is that in some of your videos, your commentary isn't up to much, it doesn't really feel like you're engaging with the audience which I understand as I come across that problem too
It's something we get used to over time!
Overall I think your channel is great and I hope this feedback helped you
