The windy snow section is honestly not that bad if you play it safe because you won't fall all the way down if you do.
But still, the last section is another hell on its own because while the sections themselves aren't very hard, most misses will bring you down to the start of the checkpoint, so you don't get a lot of chances to practice the jumps.
