I think the loop animation has to be improved a bit. I don't like after he's done laughing. Maybe you could make it look like he's getting up off the floor instead of his head spinning the way it does?
You know, I'm in love with the first rofl emote, but I could totally see this one being added to the list as well. I wouldn't really want to throw out the old design, just add this one instead, maybe as a :roflmao:.
