Do I need a revision? My left breast is sitting much higher than the right (Photo)

Your implant has not yet dropped. it might drop with wearing the breast band, oral Accolate and, external ultrasound treatments. Go back to your surgeon and ask for this. Otherwise, surgery will be needed later if it does not drop. some women may take up to 6 months to drop.

Your 1,2,3m progression photos show a normal progression of the implants being high and migrating lower. The left breast has settled into a nice position. The right breast has maybe gone too low.
There are baseline asymmetries - the left breast is a little fuller, more sternal fullness, the right breast is a little lower. We always say they're sisters not twins. An exam would give a better sense if it's implant position or baseline asymmetries but if you're not happy you could consider a revision to improve the implant position. I would wait at least 6 months before doing a revision. If you don't feel your surgeon is receptive it might be best to seek a second opinion even if it cost more.

In your before photograph, your breasts were asymmetrical, pointing outward and wider than the chest wall. It would have been better if you would have had a circumareola lift to reposition the nipple-areola complex and place the implants through the same incision. I recommend waiting 6 months from the date of surgery before doing any revision. I would recommend a circumareola lift to reposition the nipple-areola complex to achieve better symmetry.
