Possibly the boringest "talking heads page" ever, but I wasn't going to do two pages of tricky perspective in a row. :P You'll get more interesting shots in the next page, I promise. Also, considering the amount of time I spent on it, the hair in this page doesn't look too great. Oh well.
Nice shading on the hands! Also, the faces are looking pretty good, especially the cop... The only criticism I have is that the ears could be bigger (almost as long as the nose) and you could work on defining the teeth and corners of the mouths a bit better (with outlines). I was a little confused at first because I thought his mouth was closed, and didn't know what to make of the extra pair of lips underneath
Hands is one of the things I've been practising over the hiatus, so I'm glad it paid off ;) And yeah, the mouths aren't too great. I guess I don't pay that much attention to them in general, and then on this page it's particularly bad. Next thing to practice, I suppose ;)
