Pieces of work to send - Eye chart

I thought I would include a piece from my image module. 

I was proud of this response, it worked, and communicates exactly what the function is. 

I am a bit worried that all the work that I am presenting is vector work, produced on illustrator. 

Does this show a lack of diversity?

I think, to bump it up, I am going to produce a few pieces of my own, in my own style so that it will appeal to a more diverse range. 

I will email John and ask him about this...
