Markings on head? Yardage for partial?

I've changed the markings on the head a few times, but I feel like this is what I'm most comfortable with. I would like some suggestions though :)) The camel color is a tiny bit darker than the color I used here. This is my first head but I'm working hard on it, I really want it to come out nice!

I'm 5 foot 2 inches, average build. I was wondering about how much fur, in total, I would need for a partial? At least an estimate, I don't want to over spend, and I def don't want to buy too little! My partial will include: hand + arm sleeves, tail, and digitigrade legs that go up to my waist. Thanks!!!
