If you don't want to get next to it, get a manual pole saw, two extensions. Cut all the small stuff from above the prop branches. It will be easy, willow is soft. Then using the same saw, cut a snap cut (Overlap cut) in the left prop. Before you cut, tie a rope to it. Once you have the cuts made, just pull (either manually or with a vehicle) and it should break and the log will come down. If you don't mind getting closer, cut it off the stump and begin undercutting the log. Once you have a couple of rounds off, , it should pull over if you pull to the left (looking from the stump).
