Using a Clay model as a sculpture reference

I usually just work from a printed image when sculpting a figure but sometimes i spend the time to sculpt in clay first. I do this if i think i need more of a 3 dimensional reference. This clay is water based ciln fire clay unfired. If i want to reuse it i just throw it in water and let it get soft again. I prefer to use oil based plastalene clay.
     This sculpture i titled "Where's my dog?" if you squint your eyes and look at the image on the left you might find the dog.
