Thanks for entering our logo contest. I like that you offered two different layout ideas. Your emblem looks a little like a question mark, which is interesting but I don't think it works here. I posted some general feedback for everyone. Let me know what you think.
We like the symbol you created in #50 and would like to see the text "Operation Vapor" wrapped around it--giving it the feel of a stamp or a seal. Include the tagline only if you feel it adds to or works well with your design.
