GFX looks good to me, could be a little bit more professional font wise.
You should create a channel description so people can find out about you and what the channel is about.
Also you should add featured channels as this will make you appear on others channels getting you seen.
Video titles look okay, good enough for someone to not click off the video, thumbnails definitely need improving. Remember there are plenty of tutorials online that can help you with that.
Microphone volume could be increased, commentary could be better. Remember you can trim out stuttering and pauses. This will increase viewer time. Background music will also add a nice touch to the video(make sure it is copyright free; NCS is good)
Video quality is good. Video description could also be improved.
I don't mean to moan at you, I am just trying to help. Remember being out of the YouTube scene for a while can have quite an effect on you.
I see potential; keep it up.
Many thanks,
