3d garden animation

I have made a 3d animation in Cinema 4d, but it crashed in the long run. Please see attachment, for 3d rendering that has made so far including requirement file. Text that is marked red is feedback on current 3d animation. Numbers are connected with 1d drawing attached. If you have any questions, please let me know. Project has to be delivered on a very short term. Deadline is 4 december 2011. If you have any questions, please let me know.
