Judging by your channel you already have a good start. 200 subs - nice
and congrats.
Maybe step back and take an over view of what you have already done and see what has the most views / comments etc.
Doing this may show you what is working and what isn't. The ones that have the most views - maybe start tweaking that into a niche (show).
Also - look back and see what was the most fun to make - a certain character ? subject matter ? Do more of that. Chances are the ones that were more fun to make are also you most popular ones.
I am not saying that the views are the most important, just to use them as a measurement.
Maybe even make a video that asks your subscribers what ones where their favs. Maybe make it a game. Pick 3 and make a poll to see what was their favorite.
Btw: your link to your channel is broken, I was able to get to it through your twitter page. You may want to fix that
Hope this helps.
