Character Design - Knockout Mouse

So basically, I was reading an article about a "knockout mouse" (which is totally a real thing, thank you wikipedia) and thought, "That would be a cool name for a cartoon." So I came up with this guy. I was trying to create a character that was definitely not cute and did not resemble a certain famous cartoon mouse in any way. I guess I succeeded. I wouldn't want to meet this mouse in a dark alley.
