I think it is a great improvement because you removed some of the less impressive images. I am in the process of doing the same thing and it can be painful. The overall effect is far better.
I don't really like spawning a new window for each gallery. I spent 30 seconds on the new window looking for a link to go back to the homepage. Generally you should only open a new window when you are sending your viewer to a new website.
* I don't like the logos from W3C and Firefox.
* In your intro text, you mention your gold buttons, although I think you said you got rid of them.
* Some of your images look a bit over-processed: My Webpagehttp://www.myrsphoto.com/Galleries/Oklahoma/slides/568.html http://www.myrsphoto.com/Galleries/Oklahoma/slides/10.html
I would be more gentle with the unsharp mask and contrast enhancement.
* You have some significant problems with fonts and font sizes. If you are using different fonts and sizes deliberately, it isn't working.
MORE ON FONTS
It appears that you are mixing verdana and arial with different sizes. If I had to guess, I would think you are struggling with consistently applying your styles in your editor. Pick one font for text and, if you must, another for headings. More than two fonts on a page is very difficult to make look good. You used a non-serifed font for your paragraph text and then a serifed font for your headings. You have it backwards. While there are no hard and fast rules in typesetting, this is one rule you probably shouldn't break.
Non-serifed: Arial, Verdana, Geneva
Serifed: Times, Times New Roman, Georgia
Typically, serifed fonts are used to improve readability in paragraphs while non-serifed fonts are used to improve readability in titles or lists.
I really like your Alaska Photographs. In my opinion, they stand out as your best. I like this one.
I would include only one of the Exit Glacier, Kenai Fijords images. They are a bit repetitive.
