When you say it's a prototype it means this is not the real sculpture? It's just to give you an idea how to make one bigger? This sculpture, could you sell it when finished???? Thank you for all of your information. It's really interesting. How long could this sculpture last if taken care of and how do we take care of it? AND if you take out the screws, will it be able to stand elsewhere , like on a flat surface? THAN YOU :)
