Siobhan,
Looking at gorgeous girls with hourglass figures and getting depressed is what most women experience at some stage in their lives, so why should you be any different? Learning how to cope with it and getting on with life and enjoying it is the real trick.
Try looking at women in the street who don't look that good (and there are plenty of them out there) and consider how they must feel when they look at you looking slim, elegant and gorgeous, in your killer heels. You have received the compliments, you said so yourself, so enjoy them.
As for getting good photos! I often despair at trying to capture that attractive image I sometimes see in the mirror. For a start we're looking at a mirror image and nobody has an asymmetrical face. So, try uploading the photos into your computer and flopping them so you see a mirror image.
The other thing is good lighting and getting someone to take a lot of photos of you one after the other rather than you holding an iPhone at arm's length with your head tilted slightly backwards. Discard the crap ones and keep the good ones. Your avatar photo has been taken in terrible lighting conditions but still your feminine beauty shines through. You have an advantage many can only dream of.
I remember being at a party years ago where the host (who was a bit weird anyway) always had a movie camera set up on a tripod to film his guests. It was just left to do its thing. I hated it and always slunk around in the shadows to avoid being filmed.
When the tape ran out (yes it was that long ago) he would get everyone to gather around to watch the movie I sat there hoping I had somehow avoided the camera's lens.
Usually, there I was in the shadows looking as awkward as I felt. It was the thought of being filmed. However, on one occasion I had arrived at the party a little late and had actually forgotten he would have the camera going. Towards the end of the evening (2am), we sat and watched the movie and there were my friends all having a wonderful time. Then I was aware of this quite attractive blonde off to the left with her back to the camera talking and having fun. She was so feminine, all her gestures were perfect, she looked gorgeous in profile and I said to my best friend: "Who's that?"
Her reply shocked me. She said: "It's you, you idiot!" I watched in stunned silence as this girl moved around the room with such feminine grace, talking to people and enjoying herself. She turned toward the camera... and it was me, i couldn't believe it. I was seeing me as perhaps others saw me. My friend, whom I had always been envious of, said: "Now, do you see I have been telling you the truth, you're gorgeous."
I sometimes wonder where those tapes are now! (Note to self: Must check YouTube)

Recently, my cousin and I were sifting through some of her old photos from years ago when we happened across some photos she and her husband had taken of me during a visit in the 1990s. I had never seen these photos before. Even I thought I looked stunning, but I can assure you that at the time they were taken I know I was full of insecurities and self-doubt and tried to avoid looking in mirrors.
Now, as I write this I think yes, I was gorgeous then, but look at me now! WILL I EVER LEARN???

So you're not alone, Siobhan! Most of us have experienced what you are going through at same stage in our transition. Sadly, some of us will always feel this way.
You look fantastic, girl, enjoy it. If you don't, 10 years from now you'll look back at photos taken now and think: "Wow, I was gorgeous then, how come I couldn't see it?"
Stay sweet
Caroline
