The features are a tad unrealistic. I understand the feeling you're trying to get with the eyes, but I'm not seeing a human when I look at this anymore. A good thing I always go by when drawing faces is that the eyes(on a normal person) should not be more than one eye apart. So if both eyes are 6 pixels wide, I try not to make them any more than 6 pixels apart(aside from if I'm forshortening, or the angle permits them to be closer, without them seeming closer). However, the eyes are really small, and really far apart. They are also cross-eyed. The head itself has a good outline. Also... Kowalski is the name of a penguin from "Penguins of Madagascar". I just reckoned I'd tell you that.

The mouth is too close to the nose, and the nose extends further out in one side than the other. One side is also rounder than the other.

As for the story, it's pretty overused. Now that you've made him a mass-murderer, you have to give him some sort of reasonable way to stay out of prison. Not being caught is rare in this time-period, or rather the FBI and government agencies make it seem that way. Not only that, but you now have to find a new motivation, because if you make the story about him just being in war, it'll be very boring. Unless you're one of those writers who can make everything sound edgy, which is a hard status to reach.

I suggest you add some sort of twist to the story, something that'll make me say, "Really!?" because this is the classic Twisted Metal character background. Murdering someone, or being deformed(mentally or physically). It has the potential to be a good story if you add some sort of twist. Mass killing of close family members is common in many pieces in action, these are the heartless, and cold people. Either they do it out of duty, or out of insanity. However, mass killing isn't a good background. It's like making a zombie movie, that has characters that are counterparts to another movie, and have a slightly editted script.

References to the use of mass-murder to show spite(of emotion):
Itachi
Basically every character in Twisted Metal
Saw

The idea is just a bit bland nowadays. It may have struck fear into the hearts of fellow movie-goers/book-readers of the early 1900's but it's just not scary anymore. Especially since most people figure they'll find some random house blunt in a split second if they see him.

I recommend this to you, and all story-writers/bards(if you will) to listen to Shakespeare and Dragons: Worldbuilding 101 Podcast. One of the best tutorials of being a writer that I've ever listened to, it applies logic to everything, so that you can avoid things like a nonsensical story, or unnecessary side-plots.
