http://freetexthost.com/0nxm24nslyTL;dr: The legs on the boaralis sugi and new sprite are fucked up: The key points are this: on a real boar and on the original artwork, only the elbow down on the front leg actually extends from the body, on the sugi, the entire leg, shoulder down, protrudes out. The back leg is obviously different, so I'm not going to explain that. Lastly, on the sugi, the shape of the bottom edge is very different, look at the yellow line
