For clarity, knowing what these elements stand for helps put things into perspective:
<ul> Unorded List (Bulleted list items)
<ol> Ordered List (Numbered / Lettered list items)
<li> List Item
Thus, you can't say, "Here's a list item" without first saying "Here's a List". Browsers might be able to pick up the <li> and run with it guessing at what you mean, but it's no correct. That and the last thing you want is a web browser guessing at what you markup means!
Design wise it looks nice, but could probably benefit from more attention to the typography. Sizes, weights, italics and whitespace usage could be better IMHO. Things just look a little too bunched up and over styled. Pushing out the line spacing a little further and pulling those separating lines back in to sit flush with the edges of the paragraphs would help. The italic treatment on the dates seems overthought. Italics don't work too well with small sans-serif type faces, especially those presenting technically orientated data like a date (small italic sans-serif numbers are a pet hate of mine, others may very well disagree). The sub titles look ok at the moment but might be served better at a larger size. Play with it some and see how it feels.
The menu treatments could also use a little polish. The hover border-left is too close to the text and it appears suffocated and cramped. Add a little more padding in there and it should be fine.
That "Heart of Fire" block irks me. Just seems way too over styled. The dashed outline is out of context (or simply lacking context) and the pink backing kills that nice semi-transparent feel you've got going on with the background image. Perhaps this would be better served by removing the outline and background color but giving it some punch though a different type face and a larger font size. I'd also suggest you consider simplifying the text, it's a tad long winded for such a simplistic introduction. Be witty, but be brief.
Furthermore, why not get down and funk with the title "le coeur feu". It looks like it's been set in Tahoma or some other mundane body typeface and it just feels, blah. Get funky, get bold, but also try and keep it simple. Simplistically bold or elegant perhaps?
As for the background, I luuuuv the image. Nice colours, perhaps a tad blurry, but the only way you're likely to fix that is to shrink and sharpen it some (which might work well, big isn't always better, as much as I'd like it to be). I'm a tad miffed that the nice fat green stripe doesn't reach the edge of my browser window (res: 1280x960 ua:firefox). There also seems to be some nasty clipping issues happening when I resize the window (in regards to the background at least). Not sure what the problem is as I don't have time to peek at the code but I'm sure you'll get it sorted.
You might also want to try it with background-position:fixed (background will stay in place as content scrolls over). Just and idea to play a little more on that sweet transparent effect you've got going on there.
The copyright box... Nix it. Keep the copyright message by all means, you're entitled to it, but the box isn't doing your design any favours. It's dark, over styled anchor and the content within it looks like a fish-out-of-water. A simple seperating line might work better, as would some additional whitespace below the copyright message to add a little breathing space (or eye resting space if you prefer not to inhale your websites) About half that of the whitespace employed at the top of the page would be enough.
Colour wise I think it's perfect. It feels like you plucked the pallet right from the feature photography - maintaining a good relationship between element colours and the depth of elements in the photo. Nice work.
Oh and of course, take all that a grain of salt.
