This turned out beautiful! I am so glad you did this contest, because it was how I found out about you! And I'm glad the winner is so excited and deserving! I love the way the pony's hair lays against her raised leg! Very pretty!
Start by getting some supper sculpey and let your fingers get used to the texture and feel of it. Then start trying to form shapes and you will get a feel of how to push and work the clay. After you are comfortable with that and making simple shapes, get some craft wire and make a little wire stick figure in the shape of what you want and mold the clay into shape around it. The wire will make the clay hold its shape while cooking. The more you do this the better you will be.
