I think the body is pretty good but I don't like the face.
The biggest part I dislike it the nose. It's just not cow like and it isn't even the same as the old one!
Cow noses go all the way down to the upper lip and cows do NOT have a splitted upper lip! At least that should be corrected.
I also don't like the large lower lip and the old face was much slimmer. And the ears! A bit more detail like hair insede would be great and pointing up - right now they look like old leather rags.
And the hole in the middle of their hump hair is kinda strange - so is their forehead hair.
I tried painting over the face to show what I would like my tauren to look

I put the horns a bit small and up and the forehead hair didn't really work out for me but it really dosn't look good in the new model.
I made a more cow like nose, smaller lips, chin and nose, worked a bit on the cheeks. Also I made the eyes smaller and the eyebrows as well. And I made the whole mouth smaller, the lips look more canine like than bovine like. (lower pictures)
The last thing I changed were the ears. Pointing upwards and more detail.
I know everyone has a different taste but the part with the nose is just simple wrong. I hope they correct at least the splitted upper lip. Every thing else is not so important for me x)
