For Asian trans women interested in FFS, I believe that rhinoplasty and brow bossing reduction are essential. And in your case I think that also holds true. While your brow ridge is within the range for Caucasian women, it's not within the range for Asian women. And although your nose isn't overly masculine, it doesn't look to me like an Asian woman's nose either.
As for jaw work... take a look at this image of a cis woman who got jaw work done in Korea:

As you can see, she had a very wide jaw. But clearly she still looks female, even in the 'before' photo. It's normal for Asian women to have wide jaws! It's an ethnic trait - Asian women naturally have wider jaws than western women. These days though it's becoming increasingly popular for women in Korea to have jaw reduction surgery. But I think in this case the woman went a little too far and the end result looks unnatural. So I'd caution you about getting work done on your jaw and chin that you may not necessarily need.
I'm Asian too, and I had FFS that consisted primarily of forehead work and rhinoplasty. My nose looked
way more masculine than yours before my FFS. And my forehead probably looked about the same. Even now, I think my jaw looks wider than yours (lots of buccal cheek fat doesn't help, lol). But I opted not to do any chin/jaw work when I had my FFS. And despite that, I have no problems passing - I'm instantly gendered as female in every situation these days, even without makeup. Maybe I'll change my mind in the future about jaw work, but I'm pretty happy with how I look now. If I did get it done later, it would be for chasing beauty, not for help in passing.
As for costs, expect to pay anywhere from $20k to $40k USD depending on which surgeon you go to. And when you have your consultations with FFS surgeons, ask them to show you before and after photos of their Asian patients. Ask them how many surgeries they've done on Asians. And ask them if they understand the aesthetic differences between Asian faces and western faces. Good luck!
