Mockup files are everywhere, from the latest phones, to billboards. As well as being great for presentation purposes, they are a quick and easy solution to see whether the design actually looks good within the surrounding it was intended for.
Here we have the new iPhone 5c mockup, in my favorite available color, green. The color can be changed with just the click of a button, and the mock-up itself can be resized to any size you wish. The download is completely free for both commercial and personal purposes.
