Been on hormones for more than 13 yrs and I can confirm that sometimes, just making a change, like taking a new hormone (progesterone) or increasing your dose of estrogen or changing the route of administration can make a huge difference in how much fat you store, how your face/body looks, breast size, etc. At those low E2 values, I wouldn't expect that much to happen so yea, increasing the dose may help or not, also depends on genetics, your lifestyle, etc.
Also, remember, what you see is not reality but the old 'you', old impressions don't ever die and superimpose on WHAT IS. I can still see the old me, after 13 yrs and I clearly pass as cis so yea. Some days though, I see a girl in the mirror so it also depends but the more I stare in the mirror, the worst it is, LOL.
