If you want my honest opinion, you're going the wrong way. I am probably the biggest watcher of lets plays on the website, and so far from what I've seen, calling your content mediocre is kind.
It's nice that you're trying to do this, but people don't want a "lets view" whatever this bullcrap is. I watch lets plays because it's fun watching someone experience the game for the first time. You're explaining the game while playing it, what's the point of that?
Lets players joins a game blind, and if you've played too many games, perhaps the journey of a lets player isn't for you. But this "lets view" crap isn't going to get you popularity.
Beyond the horrible game choice, and that you aren't lets playing right, your attitude and tone of voice need a real change. If you compare lets players, you're gonna need confidence in your voice if you're gonna do anything. Face cam doesn't matter, it's all in your voice. You seem too weak, too timid. You know what you're saying, but the emotion isn't there.
Start with some indie horror games. Arcade games aren't meant for lets plays unless they're lulz lets plays. And I'm certain you're not heading in that direction.
