Nice. I looked up Zomboy real quick to have something to compare to, and this looks like a much more realistic version of it. The body looks realistic, all with the right proportions and shapes apart from those square fingers and obviously the face, though strangely the fingers stick out more as unreal. I like the expression, that doesn't seem directly evil but rather... touch. Nice work on the teeth and eyes.
The electrical effect is probably the part that really gives the drawing live though, that looks awesome, both simple and effectual, and the lighting/shading/etc looks great. As for the background, that part clashes a bit with the character, the shapes maybe a bit too sharp, or large, simplified. I think the text would look better with some darker colors, or border effects that related to the character. Nice choice of font otherwise. Overall it looks good!
