Well, there's no real easy and quick way to make it look good to. Anyways.
Click the siccor tool and place an anchor where you want to start, your going to cut the things you want out. Continue placing anchors around him, and when you come around full circle, click the anchor you started with and click on the inside of the piece you want to cut out. Then right click, and click cut, then he is gone. Delete everything in backgrounds, put yours in, and click paste (Make sure you didn't copy/cut over your cut out person/thing). And there you have it.
Come to think of it... I should make a tut on this.
