There are two new type of pigs: Maximilian Veer and Viper Prope Droid. Popping Viper Prope Droid is quite hard.
This level is not hard to win, but some pigs may be tricky.
Send Han Solo low into the snow, shoot the small wooden block holding up the tall tower. A good shot will destroy the block and cause the tower to collapsed to the left tower. All pigs will be destroyed.
