the most important within FFS, at lest to me, seems factor of pushing the envelope as far as one can and at the same time keeping the natural and true look of that person's character, so that they do not end up like a plastic representation of female, as a caricature of sorts.
As you can see the girls here do represent good examples, however a lot bares on individual them selves, projection of brow-bone, profile silhouette, how masculine it already is.
For some, absolute femininity will be illusive and as I am finding out, FFS is really a several follow up surgical interventions rather then one step process.
I was extremely fortunate to have Lazaro do work on my face, but in order to achieve perfection I envisioned, it will still take couple more trips to Guadalajara.
Research and look at the results, and then talk to the surgeons hem selves, this is how I came to choose Lazaro over ones I have spoken with, he was the most human and sympathetic person I had pleasure to speak with besides seeing tangible effect of his work.
Good luck hon!
