IMDB Movie Analysis

Hi Team, Please be informed that I have submitted 5th Project that is IMDB movie analysis on scheduled time without any delay and also included all the files required for submission but, after submission the result is Great!(with 36/40 Marks). Iam not understanding what mistake i have done or what skills iam lacking in this project.So, can you please let me know the reason behind this and also provide me a detailed report so that I can analyse where I have gone Wrong and rectify it in my next Project.
