I usually say that pitbulls look like the chased an oncoming semi and caught it...but that outfit! The hat is so perfect, and the cigarette, even though I can't stand smokers, it's so perfectly in character, like something out of Dick Tracey, I love it!
I like the expression and his slight smirk; it gives an impression that the dog is indeed devious and sinister. I also like the mafia outfit and hat, emphasizing he's not one to mess with, along with the cigarette. Very nice work, Jen! ^^
