They sure look cool, but it's really difficult to read the statistics. Maybe also make them about Halo if you have the spartan because the bird in the second one doesn't relate to Halo. The text is hard to read and the images are blurry. Make them 500px by 200px and they won't be so blurry.
Get rid of your text on the middle and right side and then crops it down (ice dragon one). Anyways, look at tutorials. Get better.
