I had an email from a design studio I worked with on my last commissiom. They said the author didn't make clear what he wanted when he asked for a shellfish as a thumbnail image. I had photographed my crab from a different angle to the main illustration but they really wanted a Scallop or something similar. So I created one in plasticine. I modelled the basic shape in white, then put some pink clay through a pasta machine and layered this on top. I then cut away strips of clay with a scalpel and incised grooves into the surface to blend it together. It's only going to appear as a small image so the detail should be sufficient.
Below the scallop shell is an image of three armatures for the current commission. They are for the hen, duck and horse. Below that are the animals at various stages of development. The horse and duck are semi-roughed out. I modelled the hen's body but decided I would need more detail for the head. So I did that separately and added it to the body in Photoshop!
