The dual color is nice... Although the exact color combos aren't my taste. I'd like the X's integrated into the name itself. A "whispy" look like you have is what I had in mind, but not as thick a font for the X's and more of an artists brushed look. Like an artist just painted the X's and they are still wet even? I look at the dual color combo again and think you ahve the eXact font slightly thicker than the eXposure. That's an idea, but the X's (I'm thinking) should be the same/color? Maybe not. Hard to tell without seeing I suppose. Color of entry #4 is appealing, but not as a background.
