This was not a pleasant experience. Half my screen (horizontally) was taken up by a blank UI element, while the actual screenshots were scrunched together on the right. It took me a while to realize that they were two screenshots next to each other. Others have mentioned the flashing UI elements - if you wanted to show that things were updating in real time, you could've added the highlight to the votes themselves, instead of flashing a big rectangular area. Also, you are biasing voters by telling them that one is 'old' while the other is 'new'. Show two screenshots (hopefully, larger than the tiny ones you have right now), in some random orders, and let people vote without bias.
