I understand you want to get your channel out there and known. But please, don't rely on SpeedSolving for getting views. As seen, the feedback eventually gets negative if you continuously spam with your videos, whether it's every one of yours or not. I do like the quality in this one, it's better than anything I could ever make. However, if you're going to make yourself a RESPECTABLE YouTuber, please be doing things that are respectable. Put work into not only your videos, but also your skills as a speedcuber. I don't enjoy watching hardware videos by people who are slow, not because I am sort of elitist, but because they have the most experience, and can make the best reviews, as they understand what is needed in a speedcube. That being said, making yourself look fast, or making videos like this are not the best videos to release. I suggest you stop making videos with a title like "Skewb School" until you get to a decent speed, which you aren't. Other than that, do what you do. Just don't make this a ground for you to self-promote. The difference between you and Feliks is that you put a lot of promotion into your videos when you post. Feliks, on the other hand, posts a video, and maybe just makes a simple comment on the content of the video, nothing that really stands out as "Pay attention to me!" Just make yourself seem a bit humbler here. We only mean the best when we criticize you, even though we may not be the best at expressing that.
Overall, I'm not discouraging you to stop making videos, but find a better way to get yourself out there in the community. If you change what you do, I can see you becoming a great video maker.
