Creating a Feminine Carriage by Elaine Sagant will get you up to speed very quickly in walk and mannerisms, helping you unlearn all that stuff you learned just to 'fit in'.
Two very valuable tips I learned from the book (and there are many more,) are: When walking, walk in a very narrow track -- as if you're walking on a narrow plank or raised kerb -- and keep your heels planted on the ground as long as possible, rather than unlocking the knee and rolling onto the ball of your foot. This helps certain desirable 'wiggles' to happen, and; When swinging the arms, turn them so the palms/wrists facce forward or a little farther out. This pulls your elbows in, moves your hands away from the body, and gives the illusion you have more hips and less waist than you really have.
These sorts of things feel phony at first, but you quickly become used to them. AND, "Perception IS Reality", as we say in the spinmeister business. That should help with the visuals.
Equally important is voice. FIRST!: it's a 'character voice' you'll be using for the rest of your life -- think learning how to 'do' Bugs Bunny or one of the other voices created by the late, great Mel Blanc, and then using that voice for everything. Some are able to pick their female voice up on their own, some after buying and practicing with a 'Female Voice' CD or two, some need time with a therapist. But voice IS important. Do what it takes to learn a female voice. And remember, surgery is the last, final resort only after you've used a competent voice therapist with experience helping TG/TSs develop female voices.
I hope this gets you pointed in the right direction. May the worst of your transition be over now and the road ahead be mostly sunny, clear and warm.
