I will give you 81/2 /10 for this assignment. You did not state where you got the information from therefore i deducted 1 mark. I also think that you can add more colors to the poster or make the picture bigger. That is also why i deducted the other 1/2m.
Think i will give u a 8 coz u didnt state the sources and the labels and i think ucould have used more colors.. Otherwise its gd..
