Why do people think if it's not full of swearing and dirty jokes it's "children" comedy?
I don't think that's necessarily the case. You can have adult-oriented comedy that's obscene or obscenity free, but you can't have child-oriented comedy that's obscene. I think a lot of young teenagers falsely draw from that the distinction that because of this, swearing is "grown up", and seems to dominate comedy for that audience (this is just my observation from when I was back in high school). Of course, that then polarises their opinion of clean comedy too. And a lot of brickfilmers are teenagers, so...maybe that's something to think about.
But back on the subject of this brickfilm, honestly Woodrow, Keshen's level of animation isn't inaccessible, and your brickfilming skills are actually pretty good. What you need to focus on a bit more is story: while some of your animations are funny, and I personally have no problem with your use of vulgarity, I just think your stories need to be more streamlined. I'm not saying a three-act structure, because that's very hard to do in 2 or 3 minutes, but the idea is something to bear in mind. If it's based around a joke, then a clear build-up and payoff, and don't overplay the punchline. A great source of inspiration as far as short structure goes is RocketJump/Freddiew. Before moving into longform projects, they mostly did one and a half, to four minute short films that, while basically existing to allow them to show off their vfx skills, had a clear sense of flow and rhythm.
One thing that I normally find helps is getting someone else to read the script before starting animating. I didn't with Avengers Tower: Invasion or Black Panther and they sucked; I did with Doctor Strange, Deadpool in Mexico and most of my Scooby-Doo videos and was far more satisfied with the end result. There were lots of things I'd missed which my friends were able to pick out and say was strong or weak about a script. I think doing so would really help you refine the stories and humour in your brickfilms, which when your actual animation is so strong is the area you need to work on most.
Hope this helps!
