I think the changes you made are a big improvement.

As for how your images look on other monitors, I have the opposite problem: my monitor is high gamut, so when I make an image look the way I want, it often looks too dark to other people and they miss many of the details that I can see clearly. There's really nothing I can do about it, except to use two monitors and test it on the regular monitor to make sure it's still acceptable.

Another issue with color perception is what kind of color profile you're using in your graphics editor when you do postwork. If you're saving your finished images with an embedded color profile, this may or may not be visible in someone else's browser. So when you save an image in Photoshop for the web, for instance, it's recommended that you choose the 'save for web and devices' and check the 'convert to sRGB' option (which is what is used in most browsers). This is quite different from the advice given for actually printing the images.
