I am not sure if I understand this question, are you asking about "canting" the bow ?
That depends on the shot, are you in the bushes, under some branches, in a blind, standing/kneeling on a logging road or trail, in a tree stand.........
Just do what feels right and practice, practice, practice...
Full draw and consistent anchor.
Pick a spot, follow through.

I know a guy that shot an elk while sitting on a stump with his bow across his knees when the elk walked in front of him and just raised it (parallel to the ground) and shot.
