Lemon Lime "Association"

This is a sketch I made to put on a notebook. The Lemon Lime "Gang" was a joke I made over the summer, but I figured some people would go off the deep end and complain about "gang-related themes" (at least in my part of the country), therefore the crossed out "GANG" and the quickly scrawled "ASSOCIATION". Please comment, this is my first submission and I'd like to know what I need to improve on.
