The first one is nice but almost too simplistic
the pic at the top doesnt flow with the rest of the page. It's too bland :-\. The second one has a lot of potential, but the blue and the brown dont flow well. The third is definetly the best, but the color scheme is almost limiting, no other colors look good on it. for example, teh green under the "vulpes design.com" bar kinda draws the eyes to it and doesnt fit. Great job though, you are an awesome designer.
