Thx for the advice i am kinda shy because i dont wanna be a squeaker xDGFX:
Eh, banner and logo. They are fine, no need to change.
FIX YOUR THUMBNAILS, they are very inconsistent and very hard to read. Make sure to keep your proportions right.
Content:
As the same as the others, make more original content. Everything you post has been posted many times over. (Especially those "new intro" videos. I hate those.
Mic:
Quiet and static, speak up, you sound a little shy.
Trailer:
Make one.
Can i have some tips for the channel trailer and im kinda running out of ideas for vids
