Looks good. Thanks for sharing your pics. Changes don't look dramatic...not super slammed and looks to be comfortable.
Can you quantify how many more watts you put down in the improved position?...and approx. what RPM?


Sounds like you are taking your training up a notch with the miles you are logging. I ride about 150 miles a week or so and no doubt taking it to 250 miles a week has to improve your performance.
Good luck.
