Simple Swapping of Heads in Attached Video (After Effects)

PENDING ATTACHMENTS: Still need to send picture(s) of woman head I have one video in which I would like to replace two character heads with pictures of my own. User will need to use either Photoshop, After Effects or another software to erase the background of pictures, resize them, recolor them to look somewhat realistic (nothing too professional as it is a video meant as a joke). Then user will need to overlay the faces onto the video and anchor them to follow movement such as with this video [login to view URL] I don't mind if video time is reduced, i.e. the beginning and end portions are cropped off, just want a bit of the scene with the man and woman. I don't mind if finishing is not professional and if faces look like they are glued on, just roughly have them move with the actor motion and that will be fine. Feel free to use one/some/all of the pictures attached; at least one of the man and at least one of the woman. PENDING ATTACHMENTS: Still need to send picture(s) of woman head
