Dock Party - [Hard]

This is my first map so please go easy. The objective in this mission is to eliminate all enemies in the house as well as on the crane further back. The undead, skeletons, and others have been illegally shipping guns across the seas, so maybe if you check one of their cargo shipments you can find some supplies to help you. Map took me about 2 hours to make and learn. Thanks! Any advice is appreciated
