Entry #4: Along with the blue background and white lettering, perhaps a touch of red and black to make it pop. And if you can use the same or similar font, which I got from MyFonts.com and is called Discharge Pro.
Entry #81: I like the design. I'm not a big fan of lightning bolts. Can you throw something else in there? I'm not sure what. Stick with red for whatever you go with though.
#99: When you send the files to me, can you please send one with a Blue background, one with a black background, one with a white background, and one with no background? Thanks,
