It's a Tachikoma, small personal AI tank from Ghost in the Shell. They were the most adorable part of the show! I loved them jus next to Saito tha sniper. So, having some experience with SuperSculpey, I've decided to sculpt one in miniature scale. But I was lazy and used chep, pre-coloured polymer clay - that was a mistake. It was sticky, too soft when I touched it, too rigid when I tried to make small details, blue color stained everything, even the pre-baked white elements. Even after baking it's not very hard - can you see a tip of a wire on the top of it's 'head' section? That's where antenna was, that has already fallen off.
I'll never use that clay again. It was a hell of a work, and the result is far from satisfactory.
