Charming emote, it really made me smile, especially the expression on the red emotes face. I've had the "ohhh, I'm going to pwn you" feeling in a cards game, I usually end up losing.
The best thing is it's a very simple animation but it's not drawn out, like many emoticons are, it's one that would look very good in the legend, not something you have to follow for half a minute, just a quick effective way of getting the point across. Th shading looks very nice too, it's not too contrasty, it's just nice and plain, really easy to look at. And that little transition is flawless, just how he put's the card down. That smug expression is brilliant!
Really sweet emote, keep up the good work.
