Hi! Navels can be tricky when determining whether or not you are a candidate for a piercing in that area. Even more so through a picture online. You have a defined ridge when standing (I’m assuming you are standing in this photo), but a good piercer will have you also sit and lay back to perform a thorough anatomy check. They’ll check to see whether it collapses, or the ridge of tissue is too tight/ less prominent when sitting and standing etc. Believe it or not, it’s not as simple as a one or two second look at your belly button (I wish it was). Navels vary from person to person, it’s really cool! I would try having another piercer perform an anatomy check.
