He needs a name; I'll take a look around some baby name sites and find something really pretentious.
Here is some old stuff for the previous concept. Same-ish characters, so a good start.
Then Cassandra came up with this awesome drawing.
This is an awesome start. He's a little doe-eyed for the character though.
Notes for Cassandra:
I really liked the idea of the collar being part of the coat. I played with that a bit. What do you think?
Also, playing with the squarish face you have. I am starting to lean towards something like the man in the corner, in blue. Although I kind of like the man in red too.
Also, mustaches were fun to play with, but I keep getting back to he muttonstache.
