Here is my first pass using "green stuff." I really like it as a modeling material. You mix a blue and yellow putty and it mixes into this green stuff . You have about an hour to sculpt it before it gets hard. I used no drawing to base this model off of. I just started sculpting to learn the material and properties of green stuff. The size of the model is a little bigger then a quater. I hope to update again soon with a more finished model!
