The height to width says mobile game on NG but the description mentioned that this is leading up to the release of a first episode.
You mention that you will have 2 other trailers; for these I recommend actually telling us what Battle Brawlers is (maybe tell us about the plot or show us how things work?) and either resize this to fit on one screen or export it threw swivel and it will do allot of that work for you.
Another thing I recommend is not saying "I made this, it took me around 2 hours-" because honestly no one cares how long it took unless it looks STUNNING, however most people will 0 vote this right away for mentioning that you put barely any time into it.
I wish you luck on your series bro!
