my first impression regarding the "about us" story is that your story is not much different from most filmmakers, so talk about who you are more specifically and why you make films (like a manifesto of sorts). Include some shots of you behind the scenes!
Content-wise, try to figure out what your goal is for the website. For instance, it seems like you want people to know who you are so you start with the about us on the main page. I think that's a good start, but your goal is also for people to watch your videos. Try putting together a reel of your work or a trailer for your latest short and putting that on the front page to get people's attention and to make them want to watch more videos.
For my documentary's website, my goal was simply for people to watch it online, so on my first page I just simply embedded the video. I could have just had a welcome page linking to info about the movie and our crew and then a link to the video, but first and foremost I just want people to press play and get interested so I chose to put it right on the front page, with additional video built further into the site.
Its your first shot so obviously, good start, I hope you are finding this thread helpful!
