Thought I'd go ahead and post this project so I could get some good feedback. I'm wanting to focus on doing some animations for awhile since my community is put on hold. Basically I'm going to animate a train going around a curve and then approaching an old wooden bridge. As the train approaches a boulder falls and destroys part of the bridge. The train stops just in time. But after a few seconds past and all seems ok, the bridge collapses under the train. Here's the storyboard.
