The feelings are interesting but they need work. I see what you were going for and I think you can do better. Trooper is pretty good, but nah, remove it, it distracts us from the emotions.

these are some of the worst examples of character modeling i have ever seen.

I liked the thing with masks representing feelings.
Good work.
The faces is a bit simple, but looks nice.

"Trooper" has nothing to do with your theme of emotions!

"Trooper" is cool, but ya need to do more of the "Emoticons of DOOM!!!" Try something happier, maybe?
