You never know how difficult something is untill you actually do it!
Seriously, I kneel down before all 3d animators. I don't think making a good animation in 3d is done faster then handdrawn animation. See handdrawn animation only needs to look good in one view, one camera. But your 3d animation needs to look good from ALL angles.
But Yeah this is only my first attempt so I'm not going to be too hard on myself :D I rendered out the progress so far, and even though it looks a bit wierd, it's still super cool to see things come to life :D
I didn't render the bridge because that would just take up to much rendertime, and it's only a work in progress:
This is the test animation I did before the render:
