for me, the water background doesn't really fit. the original with the orange text looked fine to me.
if it doesn't bother you having the name refering to water but not having any in the graphic, then leave it. you have a good name and a good original graphic, it's just how they fit together.
Remember, you can get good advice here on the forum, but in the end, you can ignore us and do what you want if you like it better.
