MsGrace and WarlockMaker both gave very sound advice.
I never had any major expectations at all when I started HRT. After having been on/off low dose HRT several times in the past for the much needed Brain-Reset, I figured if I am FINALLY going to take the trans-beast on for real, I needed to go back on HRT. Low in time led to full thanks to the great emotional relief I was getting. I can't help but to believe and to preach that The Biggest Reason for HRT is for the (hopefull) emotional relief. The rest, if any is gravy.
As for "High Standards".... The easiest and safest way to get the breasts you want is to buy them, as in a BA. With all things hormones, YMMV. As you learned, after 2 years about all the physical changes are about over.
Today, some 7 years later, I still live and present primarily as male. A male with a for real B cup. Hiding the girls is relatively easy. Trying not to hide them is sometimes a chore in male mode. So as to the OP, you can have your HRT, your breasts and still present as male.
