Hey Man,
Ok, Starting with your channel banner - I feel that it could be a bit more uniform with your avatar, The layout of your actual content could be structured a bit better, you have very decent amount of content that could fill your front page very nicely! You have custom Thumbnails which is fantastic but maybe switching them up a little bit with the Dark Souls Content & Some of the Text is a little hard to read on some of them. Your channel could really benefit with a channel trailer giving an overview of what your channel is about. Overall really nice just a few tweaks here and to really make it pop
Onto your content - Video Quality is on point
Audio is a little hard to hear sometimes - Not sure what Mic you are using, It distorts a little bit aswell but didn't distracted me from enjoying the video
Those are just some food for thought - I've gone ahead and subbed look forward to watching you grow mate
