Sweet tank! Great job! I know your name is Kakashi so if you want to see Naruto actually made by lego go to lego.cuusoo.com and support my idea! With 10,000 votes Lego will consider making it an actual theme!
first off and im just spitballing here, i think you should cover up those exposed holes on the side with something whether it be a kind of plate or a gun. Second this kind of looks like its unfinished like you should work to design the shape less square. But overall good tank. keep buildin.
