It is much too difficult to tell what the problem is by this picture. I do see the asymmetry that you are talking about but it is hard to put a finger on why it looks this way. The very best thing that you can do is to go back to the surgeon who did your surgery in the first place and tell him/her your concerns. (I am assuming that your initial surgeon was a board certified plastic surgeon...) It is very likely that time and massage will give you the result you want. Often times swelling in the immediate postoperative period can make things look less than perfect and with time and patience, they will get better. Allow 6 to 8 months before you start to intervene or you will not know what procedure cause what problem.
Good luck. I hope this helps!!
Over the internet with this very hard to diagnose issue you are better served to seek ONLY IN PERSON evaluations from surgeons!
IT looks like you have a ptosis of the right upper eyelid. Did you have your uppers done too? In the after picture, the lower lids look to be at about the same height, but the right upper lid looks half closed. You should see an oculoplastic surgeon to evaluate the lid height.
Its hard to tell for sure from your photos, but it looks like one of the lower eyelids is much higher than the other. A low dose of botox into the eyelid that is too high can often help lower the eyelid position and improve symmetry.
