At 33 and three months on HRT, I'm still partly colorblind but my vision has improved. I've had to get new glasses with a weaker prescription. My hips are getting bigger and my waist and shoulders are slimming, and I'm seeing development of breast tissue! I use a sticky bra and made some nice cleavage today, lol. And no, it's not just fat, because I haven't gained any weight!
You should do fine with starting at your age, but it all depends on what you've got to start with really. Just don't forget that body size and shape isn't everything. "Average Women" look nothing like our societally programmed concept of beauty, and being a woman is about more than aesthetic changes. Don't get me wrong, do whatever it takes to be happy with yourself, but if you're easily discouraged, it's going to be a very long and bumpy road, and it's already long and bumpy enough!
