Lot of good ways to get killed there. Mainly by listening to the advise on this board.
Since the tree is going to go into the field regardless what you need to avoid is
1) the limb breaking and driving itself into the field they can then be a bear to cut off and pull out
2) and the big one: is the tree hollow. With that much weight and lean it could "barber chair" or split several feet up and swing back at the sawyer.
I have attached a picture of how I would cut it. By leaving a heavier hinge on one side it will cause the tree to twist slightly on the stump as it falls.
It will spin the opposite direction of the arrow in the picture. With that overhanging weight it won't spin much, but enough so that limb lays down rather than hitting direct and bouncing the but or embedding itself in the ground.
I would also recommend bore cutting your back cut to take some of the risk away from it splitting it also makes sure you are on the side of the tree when you finish the back cut especially if your bar is not long enough to completely pierce the tree.
It does not look too bad, but I'm not there in person. I've cut professionally for twenty some years. If it scares you have a pro do it. Otherwise just make sure you have a clear escape path, and a saw with enough nuts and bar to get it and get out with out having to screw around. Heavy leaners are second only to wind damage as killers in my book.
If your not comfortable have someone else do it.
But if your careful, that isn't a bad fell.
Good luck, let us know how it works out.
