I think it's funny to see the humans' reactions to the descriptions of the "monsters", the fifth page in particular.
I don't get the second panel of that page...all the others are pretty obvious, but...well, I guess 'selfish, brutal and ruthless' is hard to illustrate without showing people engaging in criminal activity, but I can't figure out how what they put there even related.
I love the 'reproduction' panel, though...it's a bit more subtle than the other two, but clearer than 'selfish'.
