That's just his style dude...
I think if you are unable to make two cartoons look different than each other you are a lazy cartoonist.
AAgain, it's just their style.
Fine if you think it is okay for him to draw everything the same (I find Bob's Burgers to be way better than Sanjay and Craig) than that's fine.
-_- It's just his style, why can't you understand that?
Because other artists are able to make two different cartons lok completely different, some who work on children's shows.
Some like to stick with one style because they feel it's easier to make cartoons that way.
