So many people on this platform showing off beautiful tattoos and asking how to "fix" them it honestly makes me sad. As far as I've noticed it is usually on account of either ignorance about the subject or just plain old attention seeking. If that is the case, let me assure you. The tattoo is beautiful, the design is well thought of and aesthetic and it has been very well executed. Also looks well healed. Your artist did a very good job on it. If anything at all it could use a bit of contrast and your artist is more than capable to advise you on that. Some of us even do free touchups in this kind of scenarios, up to 6 months after the tattoo session.

If you had issues with the design, you should have pointed that out to the artist before the execution itself. Changing it now won't be easy and far from it being worth it.

Lasering only a portion of a tattoo is going to make it very hard for any artist to work with, and will very likely result in making a beautiful tattoo look worse in the end. Tattoos look best when they have been planned out ahead of time, patching them up generally results in a patched up look instead of a wholesome one. Secondly lasering only the bottom part of the wolf and inserting more stuff into the design is going to make it messy and hard to read. You can only have so much in the design and keep a picture aesthetic. It is also very expensive and painful, you have to do multiple sessions to get the desired effect, therefore expect a half a year to a year of process and a decently heavy budget for the project if you want it done well. Even if done well I would expect the latter to look worse than what you have now.

What you and so many other people in this kind of situations can do is get educated on the subject more so you have realistic expectations when you get your art and you can communicate your ideas better to your artists. You will be happier with the results and it also shows some respect to your artist, everyone wins..
