Breast augmentation issues over 1 year post op - Are there positioning issues that need corrected? (Photos)

Hi everyone, I’d really appreciate some professional opinions on my results. I had breast augmentation just over a year ago (under the muscle), and I’m concerned about the level of sagging and how low my nipples sit, with one side more noticeable than the other. I’ve attached photos—does this look within a normal range for this stage, or could it suggest something like bottoming out or implant positioning issues? Also, what options would typically be considered for correction? Any advice is appreciated, thank you.
