How should a make a smaller model?

so i made a 5 ft 7in sculpture of a giraffe that's abstract looking, which i welded out of mild steel in my welding cl. it is a very popular piece of mine but i do not want to sell it, however there has been a big interest in buying a smaller version of it. the only thing is, i don't know out of what material i should use, something that i can easily make several copies out of, i no longer have access to the welding equipment because it was for a cl. i thought of perhaps making a mold and doing an iron pour, but i don't really have the equipment for that either.. unfortunately i'm very limited.. the piece itself is geometric is shape in that it was made of plates of metal, not any sphere organic shapes, it is very whimsical in design, representing the playful attitude of a newborn giraffe, that is awkwardly standing. the neck is as if it was an arm with a bend like an elbow. the body itself is rather small, most of the m is the long slender legs, i would upload a picture of it here. but i don't know how to do that...
