Transforming Lerida the Taurus cow to an aurochs cow

A while ago I did a post on the Taurus cow Lerida in the Lippeaue, Germany. She is a Sayaguesa x Heck cow, and has always been among my favourite Taurus cattle individuals. Recently I used a photo of Lerida and used the program GIMP to modify her morphology so that she fits a European aurochs cow. The result is down below. The photo was provided by Matthias Scharf from the ABU.

The changes I made include: 

- horn size increased 

- horns slightly elevated viewed from frontal view 

- visible udder removed 

- trunk shortened 

- dewlap size decreased 

- hump size increased

A real aurochs cow would probably be slightly more muscular, as wild bovines usually are. But apart from that, I think the manipulated photo compared to the original shows the differences and commonalities between Lerida and an aurochs cow very well. The differences are reflected by the changes on the photo that I made, the commonalities include the colour, which is flawlessly wildtype, the skull shape, the leg length, the horn shape except for the fact that they could be more raised in frontal view producing that < >-shape, and also the body size is probably right as Taurus cows are usually around 150 to 155 cm in withers height.
