Ha, this is so interesting! The idea is clever and original, and just makes such a weird but neat little take on something as simple as dA smileys. I also like how you put it together in a comic format---it would be good as a full animation or something too, but this takes your already-quirky idea and gives it another level of oddness and creativity.
As your comments note it must have been hard to get the animations timed up right, but you did a great job. I think I especially like the last panel, with the static emote's annoyed expression; that was another great touch.
I really can't think of much to criticize here---I might have picked different emotes myself, or something minor like that, but that's really a matter of taste more than anything. Overall awesome work!
