I made it using gimp. First I did the recolouring of the full sized images and then duplicated the second image and resized, did some erasing to just get the picture of him. Did some erasing around the first one. Resized image, pasted into onto a blank document and used the first big image and desaturated it, then pasted the small color version. Did some resizing, added the text. And then cropped out the uneeded background, set the background to transparent and done! First attempt at blending so hopefully it's decent :/ the size is weird mostly since the site I'm using it on mainly has a lot of odd sized sigs.
