It probably has nothing to do with you. Views are a fickle thing. I am a guy who hardly gets views. You're popular compared to me. Hell, I'd say everybody in this forums is popular compared to me when it comes to view count.
It all boils down to many little things. It could be your taste in games hasn't been appealing. It could be the things you say. It could be that your personality isn't as charming as it was when you had many more views. I'd like to bet that it's none of the above. I'd say people just got busier and probably for the most part enjoyed what they wanted to enjoy from watching your channel and may have moved on.
Unfortunately, this could mean they would have to limit how many channels they watch, and therefore feel more inclined to watch MeleeWizard for whatever reason.
MeleeWizard could also have viewers outside of the original zelda classic member base and could also be having viewers of people not from the community, but who are just general fans and supporters of his channel.
You see, there are many variables.
Unfortunately, since I haven't seen your channel. I wouldn't have the slightest of knowledge what you're doing wrong. I'll just share my insight from personal experience, and also just from my beliefs that some times things happen for no reason, therefore it may not even be an issue of what you're doing wrong but an issue of stuff happens.
