Definitely a James Bond kind of dude. He';s awesome! This is so very original and artistic. It's something that'd be very hard to accomplish. Many can do dogs and cats as anthropology "people-like" animalia.. but a tiger or lion wearing a suit and holding a gun seems quite intense a thing to give a go of. You've done so very well!@
Really nice drawing. I think the one detail that would make it more "mafia" and less "Bond" would be to replace the small pistol and silencer (very spy-ish) with a larger caliber pistol or tommy gun. I like the pose and his face is very expressive. I like the emotion he's projecting.
