The age I think is pretty young, like 4 maybe.. its the one Arwen is riding in the first LOTR's.. He looks rather young, with a lot of care and good food in him. Slight and well padded for a stallion, I would think. That must be stardom for a horse though.. cushy barn, all the fresh hay he could eat probly..
Like what kind of areas ? would be interested to know more..

no the horse was made buy a create poly. did the outline.. thin split poly.. I did that where I wanted all the faces to be.. thin I just pulled it out like a accordion.. works fast, well, and with a damn clean poly mesh. you can kinda see me doing just that on the first page or to of the tread.. I don't remember exactly now. I have a lot more pic's of it under construction laying around also.
