YouTube has this thing called "Retention Time" that brings your videos to the front. Numbers on the surface mean nothing. What matters is when someone watches your videos, how long do they stay? You can find information like that in your analytics. Right now, having your face on your videos is very popular because it makes the video more personal. Like they're playing a game with another person. And not a voice. Sure, it's not a deal breaker. But it's sure to be a better ICE breaker. Just keep going, work on getting things like a webcam and good quality mic and learn how to edit the videos better and try different techniques. And get others you know in your personal life to check out your videos and point out the new technique you used. Get their opinions, and it might just help you fine tune what you're doing.
Just remember, NEVER GIVE UP! NEVER SURRENDER! And ALWAYS watch Galaxy Quest at least once a month for maximum motivation. Yas.
