Also I see no difference between the two pictures on the top except a little bit in the lighting.


You mean the two pictures of Uhura? The first one has obviously thicker eyebrows, smaller eyes, a bigger nose, a larger chin, a smaller upper lip, the cheekbones have been moved up a bit and I think made look a bit thicker, and there is less overall color to take the glow off her face. The one on the right is the real Zoe Saldana.
