Prometheus - David

This is an old project which has been sitting in my hard drive for almost 10 years. I recently decide to pick it up and finish it.
David is an android who pities human, but on the other hand he doesnt think human deserve to live. So I give him tear which seems doesnt belong to his expression to show the contradiction of a "crying robot". And then I also use bright lighting for his goodness , but hot red lighting for his evilness (red is common sense as caution) to convey this idea. Hope that works. If it doesnt ,then just think of that is a cheapest way for the presentation LOL.
