I have a few suggestions on the social interactions. For 1, maybe make it to were you can change the button lay out of the d pad, so you could choose favorites, or include some diagonal interactions. And 2, add some more interactions like; thumbs up, an actual wave and bow, lean (like with your back on a wall, mostly to look cool), sit(like where your legs would dangle off a cliff or chair), maybe also a forward lean so you could lean on railings. Thats all I got for now.
