In the same way as the k9 prop i am now constructing from packing cardboard a life-size (well 7 foot ish) prop of the transformers leader Optimus Prime .
started mon monday with just a few designs in my sketch book to sort out shapes and features and took it from there and decided to concentrate on the head to make first as it is the part of the whole body with the more detail.
My proto type shape for the head .
Then from my drawn out plans i started constructing the head in several pieces that then fit together.
At first i decided on a grey coloured card for the mouth plate but decided to keep the figure all shades of brown instead.
