I like #11 because it looks official and the slight gradient of color at the top makes the image look three dimensional. I'm not as tied to the map of Maryland, but it's fine. The word "Maryland" is a bit too big.
Overall I like #9, but the use of red is so prominent. I'm beginning to think I don't like red.
Entry #10 is fine, I just don't like the blue background. I prefer a white background.
