I got some great advice from this site so I wanted to post (one of) the finished products. See what you lot thought. I sculpted the original from plastaline, used a tin silicone (worked fine Mr. Mold Maker. Again, my thanks) to mold it. Cast it in an acrylic and then painted it using a base coat, wash and multiple layers of dry brush and stippling. The yellows are a bit more prominent in the pics than they are in natural light.
