Images Required

I need 5 new images creating

For each of the images can you superimpose any one of the images, in the link below, over the top of a 16 - 21 year old male or female so that it looks obvious that the image is superimposed, at the same time it also looks quite good!

These images are to promote an iPhone app that has the ability to superimpose any of the images, in the link below, over any of the users photos, hence I want it to look really good with a generic person

The 5 images must be: -

PNG Format
Portrait Orientation
1536 x 2048 pixels
Images are here: -
