8 weeks post-op and my left breast implant (right in picture) is still high compared to my right. Should I be concerned? (photo)

Dear bossbabe87,
dropping of implants is part of the healing process and this occurs after the tissues surrounding the implants slowly relax, allowing the implants to settle into their final position. It can take about four to six months for the implant to drop down to their final position.I understand that you are worried about your implants are not dropping as expected. However, you are still in the early phase of the recovery period. Please do allow some time for the healing process to occur. If after six months, you are not satisfied with the appearance of your breast, you can visit your plastic surgeon and discuss your concerns.

Congratulations on your decision to have breast augmentation! Eight weeks is still very early after breast surgery to evaluate the results. As your muscles relax, the breast implants will continue to settle and "fluff," looking different every day. These changes can occur for weeks to months after surgery. You might be left handed if your left pectoralis muscle is much tighter than the right. My patients are advised to minimize arm activity until the implants start to settle nicely. They proceed with leg and cardio routines, but avoid direct arm exercises many times. Give it time and don't be afraid to ask your board certified plastic surgeon/office for advice. Best of luck to you!

Thank you for the question and picture.
I am looking at your picture and assuming that you had your implants inserted under your muscle. If this is the case then it can take several months for the implants to fully drop to their final resting positions, although the right side appears to be pretty much there. 
In order to definitively comment it would be helpful to have seen the pre-op pictures of your breasts. If you had the volume of your breasts set low down on your chest wall and then place the implants under the muscle then you can develop a double bubble where by the implant sits higher/in the correct position and the breast tissue drops off the bottom, creating the two mound, double bubble, effect. Try wearing no bra and using a breast band over the top to try to encourage the implant on the left side to drop further, but ultimately you should consult with your Plastic Surgeon for advice and reassurance.
I wish you well and congratulations on your surgery.
Best,
Marcus
