I watched the san francisco animation, it is a lot better than the ice cream one. The start of the animation has a lot of camera movement, there shouldn`t be so much and it is a bit erratic, I know that the keyframing can be difficult using poser but less movement of the camera would be better, a simple pan into the car might have worked better. The later scenes with the car to show the passage of time would be better with the characters in the car, you could show them looking out the window or adjusting the mirror etc. Some background objects would be good, too even if it is just a simple roadway object.
