Well done - you earned that A and then some.
You have incredible talent - this is like Banksy and Monet and early Van Gogh all rolled up into your own striking style. The texture on the face is really unique, and you've captured, through an excellent use of tonal contrast, the deeply violent, unhealthy and unsettling nature of your subject. The red against black is another fantastic choice - it brings forth the threat of the fascist undertones while showing it's evolution into this horrible new world order... X.
This honestly should be hung in a museum. Get yourself an agent - I think you've got a great career ahead of you.
