I'm doing something similar to track how my newly-planted California natives are growing.
I'm taking the photos one month apart. To keep the photos similar I'm fixing the ISO and f-stop and taking them 30 minutes before sunset to reduce shadows and keep the light somewhat constant. That seems to be working pretty well. That strategy might be helpful in your case. My backend processing isn't quite as automated as yours. As each monthly photo comes in, I perform some normal processing on it and give it unique tags that I can later use to export for importing into iMovie and appending to my time-lapse movie.
