How did the first couple of posters miss the sarcasm in the subject? I doubt this fellow is so arrogant, it is simply mock superiority, a joke!
Anyway, pretty good cartoons. Inflated heads rarely look good though; for that to work, the drawing needs to be perfect in every other fashion. (Otherwise it looks like a mistake.)
Looks like you were aware of a light source while colouring, that's always good. Just be sure to study how light is cast on different surfaces. If you have a bright light on one side and a dark light on the other, the object looks quite flat.
Otherwise, quite nice work here, really good facial expressions. Tighten up the anatomy and finer details, then you're good to go!
P.S. Try to accept constructive criticism. It's very useful. Particularly Fleshlight's response. (It seemed like you shot it down without understanding it. But maybe I misunderstood your post.)
