Eyelids still drooping 3 months post ptosis surgery and upper eyelid Asian blepharoplasty. Should I be concerned? (Photo)

the lid position looks quite good and will level out after a few months. Like most patients in their fifties, ifnoring the brow is a serious impediment to a good result. Although it may suffice to remove a little more skin after full healing, a browlift will solve most of the problems related to excess skin after upper lid surgery.

It is far better to be in a situation where you need a bit more skin removed than to be in a situation where skin needs to be put into the eyelid. Due to the unpredictability of brow relaxation, it is impossible to guarantee the degree to which the eyebrow will relax. You surgeon was appropriately conservative. There is a small difference in the eyelid margin position. This may continue to improve and for that reason, I would not recommend revising the eyelid until you are 6 to 12 months out from the first surgery.

You'll likely need office revision to raise your orbito-palpebral (supra-orbital) upper eyelid crease, but would wait six to twelve months minimum to allow resolution of swelling and more complete healing.  Do not be upset with your surgeon, because he/she exercised appropriate caution.  Although it may be slightly under-done with respect to skin removal, that's much easier to correct than excessive skin removal.

I agree your right lid is lower than left. However, it appears that you still have some swelling of the upper eyelids. Swelling and inflammation often take longer to resolve after Asian Blepharoplasty. There are other considerations as well such as how the ptosis repair was done. Internal ptosis repair is more predictable and symmetry may manifest as inflammation subsides. Continue to follow up with your surgeon and allow more time for swelling to improve. If there is not improvement after 6-12 months, a revision could be considered.
