well i like them all, weve never had a proper layouter, but you might consider moving into a new style of layouts, insted of the classic with a header, nav bar, side boxes with news and links and content :| i just see too many of them, and find them a bit trendwh0rish, i really think you will improve alot, from what i have seen, they are all great designs

[edit]

you might also consider using lorum ipsum instead of "text.text.text.text.text." or "this is where the actual text will go" in my opinion, it looks more professional, and adds intrigue if no one knows what it is just search lorum ipsum or lorem ipsum on google if you havent heard of it, and look at the first site
