for one, I would try not to think about what people expect from disney and simply make a good movie that appeals to all ages.
Ive had an idea for years that I wanted to do (and was actually trying to do it at one point back in like, 2004, even made a really lousy trailer for it using 3D animation, had a small team of people willing to help me), but was never able to flesh it out enough.
The basic idea was it was about a young boy who built a tree house in his back yard to get away from other frustrations he was dealing with from school, bullies, parents etc. he keeps having to rebuild further from home, and higher because something bad things keep happening. he eventually realises he shouldn't hide from the world, that people do miss and need him.
the characters name was Mike, here's what his design looked like.

I decided I didn't like it after a lot of people said it reminded them of harry potter. so I started from scratch on his design, but then put the whole thing on hold indefinitely.
and even though I had this idea well before these came out, I think both bridge to terribithia and where the wild things are have a lot of elements I wanted this movie to have.
it'll probably never get made. but if it does, I'd be open to letting it be hand drawn too.
