Foreveralone actually might had a nice idea even if they didn't really say it.
We are talking about youtube here. Youtube is full of people making video's. What do they want? Visual Effects! Ofcourse.
Maybe it's something totally different than you do now but I'm talking about how to make someone look younger on video or older. How to make someone look dead have bruises, cuts etc.
Personally I would love to see a video on how to look pretty as a girl without make-up. Let's get personal on this one. When my old girlfriend didn't had make-up on and didn't do her hair she still looked nice and attractive. But girls feel "naked" without make-up she told me. So this might be a challenge to show you don't even need to have make-up to look pretty.
You may hate on me for saying this but I love to say it: "Girls are ignorant"
Haha, But make video's you like to make. And don't feel an outsider on this forum we all are different but we all are youtubers and can/will help each other out here!
