Yes, my photography has improved during the last few years... Before my career, all or most technical details from film to composition to gear to printing were already resolved, and during my career, the most important field to improve (very hard!) was visual narrative...
So a few years ago (after working in photography and having shot for 25 years) I thought I had little to learn from a technical point of view... I was wrong, and the last years of learning did start for me as an accident... I was travelling, starting to like street photography more than any other kind of photography, and I just had two cameras with me: the digital one, a Pro DSLR, suddenly just wouldn't turn on and I never knew why (later, after a month, it did turn on again and it's been perfect since...) so all I had with me was my Nikon FE2 with 20, 50 and 105... My small square bag for that system -a few days after that- fell down and rolled down maybe 50 stairs: my camera's needle (meter) doesn't move since... So, I didn't want to buy a cheap digital (I wanted film images from the trip) and I took my DSLR to be serviced and just kept the FE2, but soon I couldn't know its metering in any way, though after some testing I discovered it was metering perfectly so I could use AE...
That accident was the beginning of the most exciting years to me as a photographer: these last 5 years... When I found myself without my DSLR, without handheld meter, and with a camera I thought wasn't metering as it didn't show me its metering, I discovered I had been a photographer for 25 years and I had been a pro photographer for a few years, but I didn't know how to handle light without metering it! I was shocked! I just never really NEEDED that before!
Then I had to learn to expose without metering... I had to start all that quickly (test and develop at least to see contrast on negatives) to be able to shoot again as soon as possible... I started first with direct sun, and then with shadows on sunny days, and then with overcast and indoors (not easy) trying to be able to shoot without metering... Those days taught me the huge difference in tonal range (and acceptable exposure error margin) depending on development time/film contrast... I hadn't felt that alive as a photographer for years...
Soon I got back my DSLR, but photography to me was a new thing: it was about knowing the light, instead of metering it... The process of learning continues, of course... Then, for the last two years of RF use, all my efforts could be entitled “how to be able to create the image I want instead of the image the light/film ISO recommends”... I got tired, after many years of doing it, about not being able to use the aperture I want, just because “there's too much light” and things like that: filters help but are not enough sometimes...
So my last years I've been using different films on different bodies AND knowing the light surrounding me, to be prepared to act quickly on both sides of the street: sun and shades... AND to be able to shoot an image with great DOF AND with selective focus depending on what I prefer... It implies organization and at least three bodies with fast and slow film, but the price is visual freedom, and I feel a lot better this way and it's a lot more fun to me...
It's an inmense pleasure knowing I can shoot at 1.4 or 8 on overcast or sun quickly. I find it priceless from a visual narrative point of view: sometimes selective focus can be more important than composition, as it's one more way of communicating what's relevant in a scene, and composition alone can't -sometimes- isolate subjects as much as selective focus can... The same for comparing, contrasting two different situations or subjects: when focal length and point of view can't do it as much as we'd want, those are nicely related with different amounts of focus...
So my photography has improved a lot since I have the technical ability to quickly decide aperture no matter the light.
