Self portrait, idea from Andy warhol

I was asked to do a self portrait for college.  I decided to use Andy warhol's self portrait for my inspiration,  this is what I came up with.  (original and mine). This was also the first time I have used acrylics so I was quite pleased for my first attempt. I must add,  the reason why the picture on the bottom looks unfinished, Is because,  I thought it looked more interesting like that rather than full pictures.  I believe it directs the eye to different parts of the face,  therfore giving a different perspective.
