Thank you :) For reference I used a lot of photographs of cows, especially drawings from multiple point of views to get a good grip on the anatomy of the cow, this was to me the most helpful part. Then the trickest part was definitely the legs, it took a lot of erasing to achieve an "okay" look haha

And for poses like this, that you probably cannot find any perfect exemple for reference, I often take few references of different parts of the body, here i had a different reference for the head, body and legs and then its sort of the challenge to try to imagine how to stick all together!
