Kiska, here's my *honest* take on it

I tend to be a bit blunt in these things, mainly because beating around the bush isn't going to help - it's just like the challenges here. Honest critiques help us all hone our abilities; less than honest critiques may make the critiquer feel better by "not being mean," but they actually do a disservice to the other person in my opinion. I do understand that this was the designer's first site, and many beginner's mistakes were made - that's all normal and to be expected. The designer does show great potential... that said, here we go:
1) there is no usefulness in a splash page - all it's doing is adding a level between the customer and the info they want. From an Accessibility point-of-view, there is no ALT tag data on the bitmaps, thereby rendering the page useless to search engines, people with poor vision, those who have images turned off in their browsers, or those using a pure text browser. Yes, I know that photography sites deal with a visual medium, but not everyone can see. Why discriminate against them? Would you have a sign at the photo studio saying "Well-sighted people only; blind people or people with glasses/poor vision need not enter"? That's essentially what you're doing when you design your site to be inaccessible.
2) upon entering the site, all you've got is blank squares. This is what's known as "mystery meat navigiation" in the industry. The designer is not giving any impetus for the customer to go any further. Why should I click on something that I don't know what it is (especially these days where just visiting a site can install spyware and viruses)? How am I supposed to know that's a rollover image? It gives the feeling to the visitor that you don't want me here and you don't want to show/tell me anything. You don't build a site to make the end-user have to work or guess at what you're all about. The designer needs to do the work to make it appealing to the customer.
Now while it is a good thing to have negative (white) space, there is no need to have a purely vertical navigation with nothing else on the page - This can all fit horizontally. Some people in a hurry won't bother to scroll down a page; they'll just see what comes up on the first screen and if there's nothing of interest, they leave.
Now, again, you've just set another barrier to the customer... i.e., What? I had to hit a useless spash page to "enter" the site, yet on entering I'm presented with yet another splash page. I have to drill down 2 levels just to get info? Why should I bother going further?
3) just choosing a random page, Info, at 800x600 resolution, you've got horizontal scroll bars for no reason. There is nothing on that page that should create scrollbars at that resolution. Again, no ALT tags on the images. Since there is no actual text to give name, address, phone #, etc, no search engine will have anything to index on the subject of the site! The font used is really indecipherable to me. The weight of the font is so thin that it almost blends into the background. That really has to be redone.
4) This is just a big pet peeve of mine. Why, oh why do people go out and get their own domain name (khmphoto.com in this case) and then put up an email address for someplace else? You own the domain name, use it! It's another form of advertising - it should be on biz cards, flyers, invoices, etc - If you just gave me an email address of say,
dude@someotherdomain.org, why would I have any knowledge that you had a website of your own at some totally different domain?
5) On the portraits page - "more to come"? Death knell. A website is not a static item. It should change and grow throughout the year. Since it *should* be changing often, it's self-evident that "more" will be coming later. If you're putting up a website, you need to make sure you've got all the content available from day one. If you don't have content for an area, say a gallery, just don't put anything up about it until you're ready. Never, ever use "coming soon" phrases because if it's not up now, why should I come back? I'm here *now*. If I go to the store to pick up lettuce and there's just a sign saying "more later," I'm heading out the door to another shop. I don't want the info/product *later*, I want it *now*. (yes, the average websurfer has the attitude of someone in the terrible twos on stuff like this)
6) Why should I have to go back to the main page just to view something else on the site? A website is not made to be a linear experience. You should have your menu system repeated on all pages so the visitor can branch off to whatever section they want at any time. You have nothing on these pages to let me just around.
That's just my initial gut reaction on these. Hopefully I've not totally upset the designer 'cause that is not my intention here.
