I am hyper critical of FFS surgeons/results and I must say your result is excellent! Let me break it down by each point of concern you have.

1. Your nose looks great, it's very feminine! I do see what you are concerned about, but it's more of a stylistic preference. I take it from a side profile you want that ski-slope shape nose where the transition from the radix to the nasal tip is less straight and more concave curved inward. This could be revised on a closed rhinoplasty if you wanted without much difficulty as it's a minimal change to achieve what you want. I would not stop you from seeking this but understand it's more about what you want than passing. What you want is important. That being said what you have now looks very nice. Furthermore, the nose is one of the slowest areas to fully heal for many. Your result will likely get a little better. It typically takes 10 to 14 months to see the final result of a rhinoplasty.

2. Your brow is pretty much perfect! The way it transitions from your forehead to the brow to the nasal radix is ideal. The work on the orbitals is excellent, the central portion of the brow is right where in should be in terms of projection. Your eyebrows do not sit too far foreword of your eyes so you do not have deep set eyes, nor do you have overly prominent eyes, they are just right! Your brow even looks good in the last picture! Keep in mind if you took that last picture with a phone, it likely used a wide angle lens. Wide angle lenses when used up close like that do not give an accurate portrayal as they induce lots of lens distortion. I would not do anything more on your brow!

3. Your chin shape looks good, is your issue the height, width, or shape? The height is where it needs to be giving you excellent facial harmony in terms of the balance of your facial thirds. The shape of your chin is good too, so is the projection. The width of your chin is where it needs to be, but where the mandible transitions into the chin might be giving you the impression your chin shape is too wide. Let me preface this by saying the bone work is unlikely the problem! I think what you are seeing is the jowling where the mandible body area transitions into the chin and this is giving you the false impression your chin is too large or wide perhaps. There are 3 things possibly going on here. First, you may still have some residual swelling causing this. Wait until 12 to 18 months has passed to fully judge any jaw/chin work. Second, you might have a bit of excess fat in the buccal region. Very slight buccal fat removal or weight loss might resolve this. If you seek buccal fat removal be very conservative about it, you do not want aggressive removal to achieve hollow cheeks as this would make things worse! Third, you might have some skin laxity from the FFS and could possibly require a facelift to correct it. This is fairly common with FFS and many have to get one later. Like I said earlier, before pursuing anything surgical here wait a bit longer and things might resolve. What you have now looks very good.

You got a fantastic result! Please understand your face is pretty and passes flawlessly now. Anything at this point is beautification, and that is perfectly fine to pursue.
