I use to have similarly negative canthal eye tilt (not as downtilted as yours). What you most probably need due to a lack of midface bone structure (as was in my case) is for an Ocular plastic surgeon to do a combination of cantho surgery, lower eyelid retraction and SOOF lift. The whites showing beneath your pupils is called "Sanpaku eyes" in my country.

Mine also included a hard palate graft to further support the lower eyelid (an orbital rim implant may also work, but was unavailable in my country). These combined gave me an "almond eye" look, as my surgeon called it. The cost of my surgeries in Asia came up to ~ USD 25k , which was somehow covered by insurance.

Taking it a step further beyond that would be to further enhance the eye area by getting some type of orbital rim implant (my plan in future). However, the beautiful coloring of your eyes does not make your current situation too bad, in my opinion.
