I know everyone has said it, but I think it’s a good tattoo.
I too have a piece that I would like to be slightly different and am working on getting changes. But I still have a lot of open space in it. I would worry about messing with it too much the way it is. I think jerry is right, trying lightening/removal before cover-up or alteration.
Good luck, I know it’s super challenging mentally to have a tat you dislike, but it really is a nice piece.
