I've been testing Yosemite for a while now, and some icons look really out of place on apps that I love / use every day. So I have replaced a few icons with more "Yosemite-like" ones. This is just a quick design, but one I quite like :)
TO INSTALL:
Download the attached png file, open it and copy the image to your clipboard, click "get info" for Evernote in your "Applications" folder in OSx, click on the little icon on the very top left, and press ⌘ + V (paste).
...enjoy your new Evernote icon! :)
