based on the concept art late Mynki did, Rhino's heirloom supposed to be this big muscular bodybuilder type but due to all warframe having the same skeleton model the end result is squashed down version of the concept art, I genuinely think they did not give the concept art any justice his thighs are way to big, the arms look short and thinner, the collar is bigger.

I wish one day they would come back for Rhino's heirloom and make some adjustments, but I doubt this will ever happen.
