Tweak existing after effects/Ciname 4D animation.

I have an animation of a circular logo dropping from behind camera to earth. Problem is the animation company who did it for me hasn't done it smoothly, and I know it is possible. You'll be given the AE session, your job is the smooth the transition. Demo movie attached, showing the slightly jerky transition for the circle arrow logo from 3D to 2D. We need to make it seamless and smooth at the 11 and a half sec mark. Might also need to add more rotation to start of 3D logo. You can give me the AE project back from rendering in high res, once I've approved a low res preview from you.
