Iteration 3.
For my next iteration, I pursued a modular approach using separate shapes for the models distinctive details with the intention of combining them to create an approximate form. This form I would then refine further using Cinema 4D’s sculpting tools. This approach yielded the best results thus far, and the finished iteration begun to take a recognisable shape.
Already, however, it was becoming evident that my goal of 7 iterations would be very hard to achieve in any meaningful way (given the labour-intensive nature of my chosen process).
