Can tell it's quickly done
I like dinosaurs as much as the next person did (when I was a kid at least) but this needed improvement. It seemed like you were trying to recall back to a time where we were more innocent and had fantasies like this. I think the coloring is meant to reflect the use of crayons. Of course, with all the cynicalness out there, it was hard to tell if this was a parody or not. My advice is to make the images and sound more clear and try to have more of a story. You should really not try to put an animation together quickly.
