(Human) Mr. Peabody, Sherman, and Penny Peterson

I thought I'd get this out of the way before I finish my other drawings...

Anywhosies, here's my human rendition of Mr. Peabody - along with my version of their casual attire.

I figured if Mr. Peabody is such a successful prodigy, he would look relatively young...
(The bow tie on his arm is just an inside-joke thing I did 'cuz my friend was being really "Fashion-conscious" about models wearing certain clothing on areas of their body that don't belong or make no sense.)

In case anyone was wondering, I tried to aim for making Sherman and Penny look 15 years old, and Mr. Peabody in his early 20s (24?)
