Well dang, I'm impressed, you've really improved it, some new comments
Why have a splash page at all? Why not just skip it and go straight to your main page.
Your main page is somewhat (very) empty, I'd put some info about you, what you're trying to accomplish with your site, an abbreviated "About Me" or so.
Well done with the consistent layout and navigation, lookin good
For the "Galleries" page, look into preloading those rollover images with either Javascript or CSS, CSS being the preferred method. Actually
here's a link for preloading with CSS, really easy too.
I would change the text on the images, I didn't even realize it was there at first, it doesn't really stand out unless you know it's there. Try adding a black drop shadow on white text, that may help.
I like the drop down menus, very nice
It's looking good all around, hope to see more of it soon
