When did you get the cover-up done? Not to sound harsh but I suggest living with it for a solid year. When you get to a point where you are asking for a cover-up of a cover-up, you need to seriously reconsider what you want, your expectations, how you are communicating with your artist(s)...the entire process.
I really like your tattoo. It's well executed and pretty. As Dan mentioned, you could add to it.
