i saw this idea in a magazine and thought i would give it a try. first i selected a background then i used a cube template, next using layers i copied the pictures of the roses onto the cube one at a time. using free transformation i sized the image close to the size of side of the cube i was placing it on. i then used image skew making sure maintain proportion was checked to shape the image to fit on the side of the cube. you have to zoom in to make sure your edges match up on the cube. i then copied the finished cube and pasted it back into the image resizing and placing them where i wanted. with the smaller cubes i adjusted their opacity. once i had everything placed where i wanted it i flattened my image
