Based on your photographs I think you look very good for 7 weeks after breast augmentation and lift. Based on your photographs I do not see bottoming out. However your implants will continue to settle to the next 6 weeks. Please wait until then to evaluate your result and of course discuss this with your plastic surgeon.
At 7 weeks postop your result is approaching final position of the implants, but sometimes a bit more settling of the implants can happen. From your photos your result appears satisfactory, but it would be easier to tell of you also had posted preop photos.
I would say that at 7 weeks after your surgery, its still a bit too early to tell the final position of your implants. I tell my patients that they tend to settle at different times and can take up to 3 months before the final results appear. At this point, allow them to reach their final position and follow up with your surgeon and discuss your concerns with him or her. Good luck!
