Looks good, but it's way out of scale. If you could apply similar techniques to something the size of a 1/6 elephant, you'd be golden.
Thats why I always thought the Woolly mammoth I have would be a good base as its 14" tall at the middle of back, may be a tiny bit short but wit6h fur and a saddle it seems like it would be good.
But I definitely wouldn't turn down that guys custom, its pretty awesome.
