I modeled the Jigabachi AV helicopter drone from Ghost in the Shell, Stand Alone Complex 2nd GIG. The rest of the progress can be viewed on my polycount thread.
I used maya to model everything with a boolean and support edge-heavy workflow. This project was intended to improve high level traditional subd skills. I now feel confident to move onto quicker non-destructive methods to improve speed without fear of building bad habits into modeling fundamentals.
