Hormones change the contours of your face by changing where your body deposits fat. They do nothing to the bony structures but, after a few years, will round things out a bit. Everyone is different but for me it took over two years to notice significant changes in the way my face looked. 7 months is still fairly early; Be patient, grasshopper :-)
Most women worry about their weight and Transwomen are no exception but I think one of the best things that you could do to capitalize on the effects of HRT is gain some weight. The fat you gain will have a tendency to find its home in, "all the right places." I started gaining about 6 months into HRT and I began to worry about it until I realized that all that weight was going to my butt, thighs, face and .... yup! The girls ;-) So have an extra serving of pasta here and there and see how wonderfully you start to fill out your jeans!
It's true that you don't really see it happening, though... I avoided looking at pics of "him" after I came out. I recently started to feel a little more comfortable looking recently; The difference is dramatic.
