Am I a good candidate for lower blephoraplasty and fat transfer? (Photos)

Based on your photos it does not appear that you have significant lower eyelid fat, though sometimes static photos can be misleading compared to what happens dynamically as you move your eyes. You do appear to have a volume deficit along your lid-cheek junction that would benefit from the addition of volume - fat grafting is as great option to achieve this.

I am not a fan of fat transfer around the eyes. It serves no purpose and there is a risk of fat embolus to the eye resulting in blindness.
