This image was created in Illustrator and PhotoShop and was inspired by the song Winter Wonderland by Jason Mraz. (Ignore the video; just listen to the song.) I created all of the images from scrap in Illustrator using the pen tool and pathfinder tool. Next, I dragged the image into Photoshop and used the smart selection tool to select all of the pictures. I put those on a new selection and the added a drop shadow to the images.
