What's wrong with channel?

[TheCitruzFruit]

Hi, I have been wondering why my channel isn't doing well lately. Please help me out and give feedback on what I am doing wrong. Thanks!

Check what is wrong on these things:
Channel banner and profile pic
Thumbnails
Video quality
Content

banner- fine, profile pic - fine, thumbnails - I would say that they stand out but I can't say for sure since I use the same style with red background,text and png layers. The music is a bit too loud for me. It's around the same level as dialogue but should be lower so can't focus as much on what you are actually talking about.
watched rainbow six funny moments

I loved the channel art looked cooled and your rainbow six video was great the hater was going off.
