well, here's my own reference sheet, where it includes both naked and clothed version of my furry horse.

now mountaineer is a normal size furry horse with the hairy hooves of a draft horse, hair that goes over his shoulder and is suppose to have blue eyes, but i commonly use black eyes instead. mountaineer's snout is suppose to be a bit lighter than his mane color, just so his mouth and nose can be more visible.

mountaineer's arm fur starts from his elbow / knee, until it surpasses his hand / hooves, they start and end with a triangular figure on both arms and legs. giving him the draft horse's fuzzy arm. he also has side burns that are often aside his cheeks, and would sometimes rest on the mane that rest on his shoulders. mountaineer is actually a mix breed between a normal blood bay horse without any white pattern and a Shire horse. he's not as big as a shire horse.

mountaineer the railroad horse is own by me.
