i give it a 6.5;
You thought about web 2.0 thats a good point, but the background has nothing todo with rose nor any game subject so it doesn't fit on the rest of the page.
The menu could use a litle more fantasy imo(Side menu)
Two navigation parts, why? a clean website looks allot profesionaler
The content is very low on the page people with a small screen will be anoyed of your site (Take the slider away or make the header a bit smaller)
The strip at the top of the page, i don't like it (
http://eu.battle.net/en/games/wow maybe something like this would look better)
The icons you've used on teh top are to serious en they don't fit the design
Hope you can do something with those suggestions (Look from an eye of a designer
)
