I love the way your channel is going. Just a couple of tips (I didn't read others comments as to not have a bias). On your thumbnails I would try using white text on the red backgrounds instead of black. I know that's your color scheme so maybe add an outline of black around the white text. I would recommend the same with your logo as well, red and black is a great combo but without a highlight color like white its rough to see. I like your logo so much that I am going to redsign it in Photoshop myself for fun. If it turns out nice I'll send it to you and you are more than welcome to use it.
