Sprites are cool and all, but they lack some animations. There isn't even an idle animation. Not only should OOO give sprites idle animations, but also, they should consider making sprites react to emotes. So for like example:

/happy causes sprites to either do a 360 spin or a backflip while making some sort of happy growl
/angry causes sprites to growl in anger
/cry causes sprites to whimper
/love makes hearts appear out of the top of the sprites head
/sleep causes the sprite to fall asleep
/burp makes the sprite burp

I know there are more emotes than this, but these are just some examples. Add more if you feel like there are some crucial ones missing.
