That is excellent progress! I'm sure it is very noticeable, especially to people who don't see you every day.
The brains takes a long time to catch up with the mirror, on both sides of the weight equation! Many of us, when we're heavier, still 'see' ourselves more slim, which is why photographs can be incredibly jarring/horrifying (our brains process an image differently than active feedback from a mirror).
In the same way, when we get slimmer, there is often a lag where we 'see' fat in the mirror and are surprised, upon being photographed or having someone else comment on it, that our bodies actually have changed and no longer match up to the mental image we have had of ourselves.
It DOES get better, but it takes time and reinforcement. That's why I take measurements and lots of pictures - because my eyes and mind lie on this subject. Now, finally, four years out of beginning, what I see in the mirror matches what I see in a photo - no more lag. But it tools months and months of seeing myself to slowly adjust my mental picture to match reality. Some do it faster, some have a lot more cognitive dissonance and trouble adjusting to the difference. It's very individual
