We need 9 70x70 icons representing 9 different moods.
The moods are: happy, sad, neutral, sick, sleepy, ecstatic, "wanna party", angry, bored.
Initially we thought of using the usual smiley, but then thought it might be interesting to use an animal's face (bear, monkey, and so on).
Anyway, you can pick whichever you decide (either smiley or animal). If it's an animal it should be the same for all moods.
Icons need to be sleek and clear considering they need to convey an emotion using only a tiny amount of pixels (70x70).
