Epic Pose

A picture from the storyboad i made for my current animation project. the gun fires a sticky substance

My character is called Hue and he is 16. The character is cool, calm and collected and he is laid back and slow. He and his twin brother spend most of their time in the laboratory in their basement. They often argue and fight over petty things.
The gun he is weilding is an old project they worked on which shootes a gooey substance that has incredibaly high sticky power? (lol, dunno how to say the last bit >.<")
