It looks great! Perhaps, since I'm trying to convey cooling off, the black lettering could reflect a faint color of red at the top (where the black is somewhat faded) and the solid black could be more of a blue - also changing the colored lines to a two tone blue?
Example #3 - too many colors. can you change the blue in the words to one of the same blues that you used in the lines above & below so that it blends better.
Example #4 - can you take out the lines & use my logo guy somehow instead? I'd like to see how that would work, either in the front of the word or slightly above center, with a space between the two words.
