Sorry for the delay. Here are the critiques:

That gigantic pop-up is a big no-no. And that intro really made me feel like I HAD to say a while… or stay forever just to get to the site. This might have just been my comp, but your animation was very laggy. I am not really sure exactly what your site is about. I read the about thing, and it just seems to be a description about an abondoned hospital. Is this an experiments site? A personal site? A portfolio? Is this a real place? Great image used, I love them, and I think the navigation is in interesting as well, but there are a few issues with it.
Hard for me to give critiques, because the atmosphere seems to be very important in this site, and I don’t have sound on my computer. Also, it was hard to understand what was the purpose of the site.
Very pleasing to look at, and an original style, but it took a long time to load. I wasn’t always quite sure when it had finished loading though, so I was probably hanging around for longer than I ought to have been. An interesting navigation choice as well. I liked it a lot, but the major concern is that some people might not get it too quickly, and have problems. I also wasn’t totally sure what the whole thing was about… I’m presuming photography, but it was a little bit of a mystery tour. But minus points for making me have a pop up window.

Oh man… do we have to do this… lol. Well I will still be 100% honest. I think the intro was kind of slow. The rollover on the bottom panel/buttons were nice. You might want to make the dynamic text for the button labels unselectable though, if you try and select it, the text shifts… sometimes out of view. I see you use the same animation between when a section loads… but it appears to be scaled up and I don’t think it looks as good scaled up, seems very jaggedy. In the The Book -> About The Book if you click the down arrow, then the up arrow it reloads the section. This happens if you hit the Up arrow until ithits hits the top of the area. In The Studio -> Sketches when you click on an image, you seem to use a black clip that fades out… but the thing is, that clip is above your navigation menu of the image, so the top part of your menu items gets cut off and faded back in. I have seen better from you, sorry if I disappointed you 
Very unconventionnal. I’m not sure I understand why you used dark colors so much, when this woman seems to be so cheerful. Also, I don’t like that kind of “dirty” look, with the videos, and the signature. Well-made, but not appealing to me.
Very Gothic colour scheme, the red and black. I also liked the menu buttons at the bottom with the kind of bitmap quality to them. One thing I noticed about the first one though was the animation comes out of the box a little. This could be intentional, but since the others don’t, just thought I’d mention it. The animations were very choppy - again this could be intentional, but I don’t know for sure.

Didn’t really “get” the intro, just some blurry image and sound, then a load bullet shot? It could use a bit more color, the black and white theme didn’t really work here, it kinda dulls down the site. I am not a real big fan of drag and drop navigation menus unless they have something to do with the transition between sections. It didn’t really have a defined layout, just a black and white image and a box with text (that I couldn’t read because I don’t speak the langauge )
I didn’t have enough time to explore the whole site, sorry.
I really liked the look and feel of this, even if I couldn’t understand the French. Menu system was easy to follow, and the disc downloading into the brain was definitely a nice touch. There are some nice transitions in there too, although they seemed very stop and start in places. Good imagery and overall I was very impressed with the simplicity of the site.

The color scheme is a bit “trendy”, but I think it looks good. Very nice simple and clear navigation for the amount of items you have (work section). The transitions were always smooth which is good. I like this site. Just as a note though: In the info section… the “y” in “University” is half cut off, you might want to fix that. I voted joelmedia because it is simplistic without being too simplistic, just the way I like it.
Cool little site, very well executed. Nothing crazy, nothing new.
Again, another fantastic looking site. Beautiful photographs. A lot of loading, but then I can imagine that those pictures are quite large files. I wasn’t immediately sure what the site was about, but once I got into it, it became a lot clearer. The Info rollover was a good idea, and I liked the draggable calendar, all very nicely done. Wonderful. I just loved it. Oh boy, it’s going to be a tough choice this week. I’ve gone for Joelmedia.
