Hey
EMPTY!
You're absolutely right about the number of big channels now! Being with Youtube for a few years is a big accomplishment!
Montages can be a great way to introduce a new viewer to your channel, but for a new viewer to watch a 11 min video might be difficult.
*I would sum it down to a few mins in video length.
It seems like you upload a vast variety of videos, which is great to those people who watch specific videos.
Your thumbnails aren't that bad, but it could use a bit of work. I understand thumbnails can be annoying to work with sometimes.
*I would try to make a bold outline on the letters to grab more attention
Overall good channel! I wish you the best of luck!
