Expressive is indeed the word for this. Well done!

Great emotes, very simple yet expressive.

I think the fro needs more contrast, but otherwise they're great

some of the better smilies I've seen in a while. I tend to jive better with simpler smilies with some basic AA. by simpler I guess I mean not doing the following:  "well I'm working with a ball so the only way is to gradient and shiny the shit out of this."

great job!

I likes, every emotion has a distinctive expression, good job dude ^-^
