very nice avatars, did you add shading to the first one? if so it looks nice. heart cube. the cake on is oka, it look like you copyed and pasted that one quickly, without covering it up though.
Meh, they are okay, but try to add some effects, they are kind of plain, the text is okay, but it could improve.
As they say, whoever says the cake is a lie hasn't finished the game. :/ I'd changed the font from "lie" to something else.
