One, how'd she react to the shot did she buck and kick then bolt? How high were you? Think shot angle. Did you see where you arrow hit the deer? Did you find thw arrow?
Does the arrow smell sweet or sour? Is there any brown or chunks of stomach matter? What angle was the deer at? Broadside, quarter to/away?
Are there bubbles in the blood? A lung hit will look punk and frothy. Muscle blood will be like fire engine red. You can have both types of blood mixing. Liver will be almost purple.
I take pictures of my blood trails, these are pics of a double lung hit last November.
