Looks good @SDTMinSTL. However, if I may suggest, some of the header images could do without the solid background color. For example, the Ghostbusters image appears square with a white background. If you do not want the solid background and box look, you can simply add "png" to your Google search. Type in "ghostbusters png" in Google image and you can find all kinds of nice PNG images without the background look.

You'll notice the checkered part behind the Ghostbusters logo, which means there is no background on that image. It's already cut out for you. In my opinion this makes your header images look much cleaner and professional. Be sure to use PNG images and not JPG or other image files. If you don't see the checked backing, then there will be a solid colored background.
Without the white background, that Ghostbusters image will look more like your Fathom, Whirlwind, and Attack From Mars headers.
