Don't take this wrong, but I think you're taking the wrong approach. If you want to be a great artist, you shouldn't be striving for fame and recognition. Fame and recognition is a side effect of doing something that you truly love and are passionate about. In general, "starting to feel like its bad, horrible, garbage, and I should stop doing it" might be a sign that this kind of activity isn't really for you, mostly because of the last point - almost a self-fulfilling prophecy of sorts.
Have you ever seen the Khan Academy intro video? Everyone starts out bad. We weren't born into this world walking on two feet. We had to fall, trip, fall over, stumble, and eventually, learn to walk mistake after mistake after mistake. If you don't believe me that this analogy translates into pretty much everything else in life - ever heard of KevJumba or Freddie Wong? They're now rich, famous YouTube stars, and FreddieW doesn't even need YouTube anymore - he's off producing webisodes with million dollar budgets, similar to Hollywood movies. But guess what? Have you seen the videos they started with? Both of them were just dorky little dudes with grainy, shaky phone cams, making goofy videos of silly stuff they found fun, like shooting obviously-fake guns at each other in FreddieW's case, or just talking about girls and Asians and whatnot in KevJumba's case.
Here's the deal. If you think this is something you want to continue doing, ask yourself if you can follow these two mantras:
1. Do it for yourself, not for others. There's almost no point in pursuing an artistic endeavor unless it's something that you can look at, be proud of, and find to be amusing - without considering what others think. This is the source of drive and passion to continue doing something over and over and over 'til the end of time.
2. Excellence is a process, not a state of being. There is no such thing as "good enough." At least, that is the philosophy you need to take if you want to become great, and not just mediocre. There is always a way to do something better, and it's up to you to find out how. The more obsessed you are with finding out how to improve, the more likely you are to achieve greatness. (This applies to all things in life. You could live your whole life working a data entry cubicle job you hate and pull in just enough to survive, or if you really love data entry, you'll find little tricks and shortcuts that will optimize your strategy, and you find better and better ways of doing something, which will give you the clout to either rise through the ranks or get a better job at a different company. Or if it's not your passion, you find something else to do where you can in fact constantly look for ways to improve).
That's my two cents anyways. Haven't watched the video yet and I might never watch it, but honestly, I say that's irrelevant to your decision, because whatever your video is like right now, it's a point in time, and the important thing is how you see this continuing into the future. If it's truly your passion, then you will inevitably improve, which means this video is no indication of your future quality. If it isn't, then no matter how good or bad your current videos are, there's no point in expecting a lot of people to watch your videos.
