Dissapointment i give my teachers !

When I go see my drawing fundermentals teacher on Thursday , i only got a few pieces of works to show him . He told me off !  Not really told me off but told me  that I always slack during his class and only show him a few sketches and expect to let him have a good impression of me. When I hear this , I felt really ashamed and also have a sudden burst of anger wanting to show him what I am really capable of . As people always say actions speak louder than words so I will prove that with my works and just by saying it. Drawing Fundermentals you are going down !
