I've had a look around and watched a couple of your videos. Here's what I think:
The content isn't bad, but there are probably a few things you could do to make the videos a little more engaging. I'll use the Tiny toons video for my example as its the one I watched most recently. Here's a few things that I think might help:
-Streamline. You can cut down on some parts of the explanations on most of the video, this way you'll reach the point quicker and get to deliver the punchlines of jokes quicker too.
-Enthusiasm. I can hear that you're trying to sound enthusiastic on parts, but sometimes it just sounds forced. Taking JonTron as an example, the reason his reactions work so well is that they are very real and human reactions to things, just very over the top. It seems like you're trying to do the over the top bit without considering the human bit. Sit and think about how you actually react to things, then crank that reaction up to 11 and show us that!
Honestly your content is well on the way to being great, but with the types of videos you're making it's going to be tough to keep a good upload schedule. And unfortunately that is very important if you want to grow. Really all you can do is keep growing and improving your videos and then share them everywhere you can! Best of luck!
