Kirth's uncles look really cute--I think that you drew them amazingly well.
Now, they have significatnly different skin tones... does that mean that one's the uncle from one side of his family, and the other from the other, or are they just in love so he sees them both as his uncles?
hm, you actually did a good job making the uncles look a bit older than the rest of them... they look, i don't know, like nice people ^^
(and the bottom left drawing is just plain cool)
