Works in my firefox. They look great. Nice job. Only thing that bothers me on the second one is the effect under the links, shows up on all the links! And I think it would benefit the layout to just have it to it on the top navigation and not every link on the page. Otherwise, I like them!
None of them look like portfolio templates. They look good, but they have the "ordinary" blog design I've seen over and over. Not that it's a bad thing.
I personally like #2 the best, but I'm not a fan of the header type in the content. It would probably fit grunge better.
