uhm, just a quick note. if that’s supposed to be a camera shake you need to change something very important. in your quicktime only the sub is “shaking” and the rest of the image is steady. in case of a camera shake the whole image would move, not only one object. right now it looks like your sub is jumping up and down.
I would suggest rendering in 10% righer resolution and adding the camera shake in your favorite compositing tool.
good luck with the rest, I’m looking forward to more updates
, I like the rain but maybe the particles for the rain drops could be a little smaller though.
