@Charmed– I'm definitely a fan of large pieces and heavy coverage. But I have to say that there is sometimes something very dramatic about a single well-placed tattoo, and yours falls into that category. It is like a single painting hanging in the middle of a wall, it sort of focuses the eye. Very pretty!
That being said, the wrapping idea sounds nice.
Alternatively, since you seem to be inclined to get more tattoos, maybe you could move to another part of your body for your next piece, and let this one sit for a while as you ponder ideas for your leg. As @Hogrider said, think about where you want to go with your leg. Do you want an integrated large piece, or a collection of pieces?
