Being that you had success on your stand their's really not much anyone can say to improve it.
but to be honest ,I feel someone could do alot of similar set-ups in my area with very poor results. Apparently early season yotes are alot easier to call in the northeast.As from what I've been told.(I wouldn't know . don't start calling until after christmas).
If I were to give this area a try I would wait until about half an hour after daylight to enter the area.than , being reasonably sure that any active coyotes would be out of the fields I would walk straight across the clearing with the wind in my face. I would pick an elevated spot about fifty or so yards into the tree line.The most important aspects would be having a clear shooting lane down wind to the field edge.This would give me a few things .It would allow me to cover my ground scent (where I walked in) and downwind in the same field of view. being fifty or so yards in the tree line should make any approaching predator feel more at ease traveling just inside the field edge to the set up. If everything worked right the yote would be shot before cutting my track or hitting my scent plume. Somewhere bwtween me and where I entered the woods
This is a very good post .looking forward to reading what others have to say.
