There is more content posted on this site on a regular basis than the average person can take the time to watch and comment, so they tend to focus on films by people whose work they've enjoyed in the past.
I don't think YouTube subscriber count is relevant here, it has more to do with who has a track record of producing quality films and posting them on this site.
It's true that unlike YouTube, 'Star Wars' and other themes aren't likely to win over a lot of people, simply because these topics have been done so many times.
At the same time, the three of your films that I could find on this site have very low framerates, sets that do not fill the entire frame, and often feature characters that are completely out of focus. We have many members here (even undoubtedly in your age range) who produce first films that look much better than this. I'm not saying anybody hates you or that you can't get better, but if you want to get more recognition on a site with a lot of good films being posted on it, the fastest way to achieve this is to work on improving the quality of your films.
Simple things like building more complete sets (whether out of LEGO or creatively out of whatever materials are available to you), attempting a higher framerate and avoiding shots that are simply still images, and making sure the shots are in focus would go a long way to improving the quality of your work.
All these same things apply to voice acting. While there is probably more demand for voice acting than this site can provide (which is why I had to rely on friends and family for voice acting for the first several years I made LEGO movies), you'll get more responses if you have a track record of making films that show you're putting some serious effort in and trying your best to produce something of quality.
You also haven't really been very involved in this site. Ten posts, most of them in the past week. The members who are well known within this site are people who have made an effort to be active in it. Of your ten posts on this site, seven are about your own projects, and three are in releases threads, which is good, but your comments are all single, short sentences. If you give others feedback and try to be a part of the community, you're more likely to get feedback on your own work.

Do you have any examples of this?
