Hey Dude
Just finished watching some of your vids. I don't know much about SEO, so I will refrain from commenting on that. Here is my overall impression:
Channel Art:
I think your channel art is of very high quality already. It looks REALLY crisp. You could consider adding some information to your channel art, like if you have a posting schedule or something like that. But generally, it is pretty flawless in terms of quality to me. I think your channel art also seems kid friendly. From watching it, even before watchin any of your videos, I would assume you have some family friendly content.
I think your thumbnails are nice overall, and cool with your own little animated guy on them. However, both in the Pedestrian and DBZ Kakarot thumbnails I am having a bit of a problem with reading the stuff in cursive. I think it would be more readable with a non cursive font.
Entertainment value:
So, I think you have some decent lets play content. And you are good at commenting without stumbeling over your words! But I am not sure how It is supposed to stand out in the sea of lets play content. I am not a big consumer of lets plays, but one I do watch is: ITemp
https://www.youtube.com/user/iTemp2. The reason for this being he does Apex content which I love, and that he has a nice energy in his commentary. In my oppinion, I would like your content to be a bit more upbeat.
I know that people want different stuff, and there is undoubtly a market for more calm lets players. Heck, there is even gameplay without commentray that is doing great. So if your style is to be more laid back, i think you should go with that.
I think you could be a bit more informative is some of your videos. Like in the Deep the Game video, I think it would have been nice to get a bit more introduction to what we as a viewer should expect of the game.
The same I think can be said in your TemTem Video. We learn that it is a: "Pokemon Like Game, but with a few different key features". I would have liked to know what these features was as you are mentioning it.
Sound Quality:
I really have no negative comments here. You have a relaxed voice, and the audio quality seems nice.

Overall, you are doing great. I had some comments, but they are really minor compared to the general positive impression I got from your channel.
I think you have the overall quality of a bigger channel, so if you manage to find your audience, I am sure you could go far
Would love your feedback on my channel if you have the time! Seems like you have a good eye for quality in general. I won't link it here, but you can find it in my profile information.
Thanks for the watch!
