Do you think my ptosis looks bad enough to undergo a surgery? (Photo)

Based on this photo, you definitely have left upper eyelid ptosis, and depending on whether you exhibit "hering's phenomenon", you may also have right upper eyelid ptosis that is currently being masked. Fixing the left eyelid ptosis, may unmask the ptosis on the right eye.
You definitely need evaluation by an ASOPRS trained Oculoplastics surgeon.

Yes, you should have ptosis surgery. I do recommend that you get more than one personal consultation with ASOPRS fellowship trained oculplastic surgeons. That is a board certified ophthalmologist who has also done an accredited fellowship in oculoplastic surgery. You really need to find a surgeon who has an aesthetic eye for this work. Study their website. Study their patient reviews. Santa Cruz is a small market. You should be prepared to travel to the Bay Area or Los Angeles to find the best work. Don't get bamboozled with a zoom consultation. Assessing someone for ptosis surgery is a hands on activity. Your eyes can be your best feature.

This is a personal decision. I do believe ptosis surgery will improve your asymmetry significantly. At the end of the day, if you are bothered enough by this, you can undergo surgery. Otherwise, you don't have to.
