Is complete removal of my new tattoo possible? Will I be left with unsightly marks? How long should I wait to begin? (Photo)

I got it only a week ago. It just didn't turn out the way I envisioned and it is too large (probably around 6"x6") and dark. I'm concerned whether removal would even be possible because of how dark it is. I've heard some doctors say it's easier to remove after at least a year, others say it's easiest after a couple months just after the skin heals. I would be open to getting a different tattoo in the same spot if I couldn't completely get rid of it or if there will be unsightly marks.
