Based on the position of your scars, I don't think there is a significant amount of bottoming out. Looking at the left lateral view, the implant looks like it may be slightly below the inframammary fold, which could indicate early bottoming out. Have you noticed a significant change in the position of the implants over the last few months? If you have noticed a difference in the past few months, it might be possible to address this with doing some work on the capsule around the implant. Another factor I would consider is the profile of the implant that you have. Again looking at the side-view photos, it looks like the nipple-areolar complex is a little above the most projected point of the implant, which can give the nipple an upward projection. If that is the case, using an implant that has a different profile (i.e. wider diameter), could elevate where the most point of maximal projection sits on the chest.
