Have ever thought about a fursuit done with metal digigrade legs that would have metal showing similar to Ziegelzeig legs and foot-paws. Reason I mention this is I have a foundry that I am using to cast silver/ gold, and Aluminum. I have working plans I am changing the parts and design to match its design made in better materials both lighter and stronger. There is an other thought change the legs so they appear metal using a 3-D printer to cover the human leg a shell like armor but resembling the artificial limbs used In the Fullmetal Alchemist but with metal looking fox foot-paw instead. It is odd but I was planning for next year at Vacoufur in Canada 2017 to unveil a fursuit but with only one leg done but now seeing your creation confirms that two legs done that way wouldn't be bad, but actually, very good.
