Insane studies as always Mike! I particularlt like the last character, great facial expression there.
As far as crits are concerned, nothing really as I'm always blinded by your progress. One point I will mention is that at times it seems as if the limbs aren't exactly as well fitted to the body as they should be (?). Sorry if that doesn't quite make sense, it's as if the elements in the shoulder areas are almost "floating" to an extent.
Keep up the great work!!
