thanks for the critique! 
I tried mostly to capture the way those characters act in the picture, which was mostly what I was going for so I'm glad you liked how they turned out ^_^
I also did try to show that they do have bad in them but the kind that is used to be in sort of, sitcom conflicts? I dunno, I see these three being in a sitcom XD
besides that, yeah I do need work on the legs (I personally didn't like them)
I think your critique is fair, hopefully I get to draw more of these characters in the future in different situations XD
again, thanks for the critique! Have a nice day
