I got the original .psd if you got photoshop...

Other then that best thing I can think of is a screenshot of photoshop with the .psd open.

And the least proving proof I can think is showing all the images I used... er... just the c4d I used and Rins. The other two I wouldn't know how to find again since I got them randomly from google and they don't look all that much the same lol.
