No, not film school, I used to post short films that I made when I was in high school, and yes, I'm in college now, but there isn't much to that.
If one doesn't already exist at your college, start up a YouTube club. When I went to college (when dinosaurs roamed the Earth), starting up a student organization was easy. It is really a good idea to have meat world people who are doing the same thing you are. You can collaborate with them. Brainstorm. Vent. Provide moral support. Help each other deal with The Dip. Etc.
As for the comedy skits, I didn't feel like I had much to bring to the table.
As Dirty Harry once said, "A man's gotta know his limitations."
I figured I'd take my youtube channel to somewhere a bit less discovered - music videos / reviews. I feel like I have much more to say, and there's a lot of room for me to grow here. I see your point in catering to a very small niche, however, that's actually what I was going for. I think that a small niche would definitely be better because of a more loyal fanbase.
Good! You've thought it out a bit. Now...
1) Add a comment to that music video's comment section and give a link to your review. Expect to be flamed by their fans.
2) Email the band directly and if they have a publicist, email him instead of band members. Tell them that you try to cover a lot of bands but any of your videos that gets a lot of Likes, you will naturally do a review of another of one of that band's songs. This might get them to tell their fans to go to your review of them and click the "Like" button.
3) Tell the bands that if they are producing a music video within X number of miles from where you live, you'd love to come by and do a behind-the-scenes video of them making their music video.
4) If the band tours and they will tour within reasonable driving distance to you, suggest you do a concert attendee video. Or even an All-Access backstage video.
It is my bet that your channel can become very successful if you can enlist the help of the publicists of the bands that you review.
As far as a specific type of music video, I dont have one yet, however, I think I should lean towards a more specific genre in order to narrow down my niche.
Good idea. As long as there are a good number of bands in that narrower niche, you should be fine. How many are a "good number"? That I cannot answer for you. It depends on how often you're going to release videos. The more frequently you release, the bigger that "good number" will need to be.
