I decided to give a Visual Upgrade to a champion I felt needed it, and a champion that I like a lot, Swain!
In retrospect, I feel that I didn't alter his look all that much, but I had a whole lot of fun working on this. As swain is a tank/mage, I decided to give him more armor on both his Human as well as his Raven form. His Raven form, specifically, felt too squishy on the old model, and seeing as how he can sustain so much in a fight, sometimes fooling his opponents to fight him longer, I decided to make him look tanky by giving him large pauldrons echoing his human form design.
I approached his other abilities by simplifying the previous shapes and making them readable from afar, and distinguishable during a teamfight. His original W, for example, Nevermove, was a little hard to see in game once you were caught. By changing the colors and simplifying the texture, it should not only read better, but it'd look super cool.
